Mit dem geplanten Start der Tropical Forest Forever Facility (TFFF) auf der COP30 im November 2025 eröffnet Brasilien die Chance, Mittel zum Schutz der Tropenwälder auszuweiten. Der Fonds, unterstützt von Tropenwald- und einigen europäischen Ländern, soll 125 Milliarden US-Dollar für Erhalt und Wiederherstellung mobilisieren. Er geht über die Kohlenstoffmarktlogik hinaus: Ziel sind konkrete Investitionen in den Waldschutz. Für messbare Vorteile für Klima und Biodiversität sind jedoch tiefgreifende strukturelle Veränderungen nötig.
Da die TFFF nicht durch Zuschüsse, sondern über Kredite und Anleihen finanziert wird, ist sie auf die Rendite-Interessen von Investor*innen ausgerichtet. Dies kann dazu führen, dass finanzielle Performance Umwelt-, Klima- und Gerechtigkeitsziele übertrumpft. Für die TFFF sollten klare Rendite-Obergrenzen festgelegt werden, sodass Profite nicht zulasten von Naturschutzzielen gehen. Es braucht Transparenzmechanismen, die das Verhältnis von finanziellen Erträgen zu Wald- und Gerechtigkeitsergebnissen zeigen. Die Zweckbindung eines Teils der Mittel als reine Zuschüsse kann dazu beitragen, dass die Ziele der Initiative nicht beeinträchtigt werden.
Die vorgeschlagenen jährlichen Zahlungen in Höhe von 4 US-Dollar pro Hektar werden dem ökologischen Wert der Wälder in Bezug auf Kohlenstoffbindung, Wasserregulierung und Biodiversität nicht gerecht. Besser wären regional differenzierte Zahlungen, die Entwaldungsdruck und Opportunitätskosten berücksichtigen, regelmäßig an Rohstoffpreise angepasst. Geld allein stoppt Entwaldung nicht, wenn die tieferliegenden Ursachen bestehen bleiben: Agrarsubventionen, die Anreize für Entwaldung schaffen, die fehlende rechtliche Anerkennung Indigener und Traditioneller Territorien (ITTs) sowie Handelsabkommen, die den Rohstoffabbau gegenüber dem Naturschutz begünstigen. Darüber hinaus muss die TFFF Investitionen ausdrücklich ausschließen, die auf die primären Wirtschaftssektoren abzielen, die die Entwaldung vorantreiben, etwa Landwirtschaft und Bergbau. Ein zu stark ökonomisierter Ansatz birgt die Gefahr, dass Wälder zu Finanzanlagen reduziert werden, die Marktschwankungen unterliegen, während die zugrundeliegenden politischen und wirtschaftlichen Ursachen der Entwaldung unberührt bleiben. Notwendig sind daher flankierende politische Reformen: die Abschaffung schädlicher Subventionen, die Einführung strengerer Vorschriften für Rohstofflieferketten und die Überarbeitung von Handelsabkommen, die Anreize für die Zerstörung von Wäldern schaffen.
Für den Erfolg der Initiative sind weitere Faktoren wichtig. Eine Überwachung mit Hilfe von Satellitendaten und unabhängigen Vor-Ort-Kontrollen, klare Referenzwerte und Messprotokolle, regelmäßige externe Audits und öffentliche Onlineplattformen zur Echtzeitüberwachung, könnten für Transparenz sorgen. Zwar müssen mindestens 20 % der Auszahlungen des Fonds an Indigene Völker und lokale Gemeinschaften (IP&LCs) fließen, die nachweislich die erfolgreicheren Waldschützer*innen sind. Aber: Ohne direkten Zugang und transparentes Rechnungswesen droht, dass die Untergrenze zur Obergrenze wird. Da Gelder derzeit vor allem an nationale Regierungen fließen, drohen politische Einflussnahme und Mittelabflüsse. Direkter Zugang für IP&LC-Vertreter*innen, zweckgebundene Konten mit öffentlicher Berichterstattung und eigene Governance-Strukturen für ITTs sind daher unerlässlich. Die Überwachung sollte ökologische Indikatoren wie Baumkronendichte und Degradierungsraten mit sozialen Metriken verbinden, darunter direkte Mittel für IP&LCs, Transparenz und Pünktlichkeit der Zahlungen, Anerkennung von ITTs sowie dynamische Entscheidungsprozesse mit regelmäßiger öffentlicher Berichterstattung.
Damit die TFFF wirksam ist, muss sie mit Artikel 2.1(c) des Pariser Abkommens verknüpft sein, der Finanzströme vorrangig auf Waldschutz, Unterstützung betroffener Gemeinschaften sowie Klimaschutz und Biodiversität statt auf Renditemaximierung ausrichtet. Dafür sind verbindliche Umweltziele, Entscheidungsgremien mit Mehrheit aus Tropenwaldländern sowie indigenen und lokalen Vertreter*innen und Folgenabschätzungen nötig, die Klima-, Biodiversitäts- und Gerechtigkeitswirkungen als Erfolgskriterien messen. Neben der Weiterentwicklung der TFFF sind zusätzliche Maßnahmen nötig, um Ressourcen zu mobilisieren und Entwaldungsursachen zu bekämpfen: strengere Vorschriften für Exporte, die im Zusammenhang mit Entwaldung stehen, und der Erlass der Auslandsschulden von Tropenwaldländern können erhebliche Ressourcen freisetzen, etwa für ein Naturschutz-Grundeinkommen.
Gerechte Wald-Governance erfordert die Umverteilung von Ressourcen und Entscheidungsmacht an diejenigen, die die Wälder vor Ort schützen, sowie politischen Willen zur Bekämpfung der strukturellen Ursachen der Entwaldung. Gelingt es, das globale Finanzsystem mit Klimazielen und den Rechten von IP&LCs in Einklang zu bringen, kann die TFFF echten Wandel bewirken – vorausgesetzt, die Profitlogik wird überwunden und eine Governance-Struktur umgesetzt, die Waldschützer*innen und IP&LCs ins Zentrum stellt und die politische Ökonomie der Entwaldung angeht.

What happens when the world’s highest court declares climate change not just a political challenge but a matter of international law? On 23 July 2025, the International Court of Justice (ICJ) issued a landmark advisory opinion that could redefine the global climate order. The momentum for this case began with a youth-led global campaign spearheaded by Pacific Islands Students Fighting Climate Change (PISFCC) and World’s Youth for Climate Justice (WYCJ). They mobilized more than 1,500 civil society groups worldwide and successfully persuaded the United Nations General Assembly to adopt the resolution requesting the advisory opinion. The government of Vanuatu successfully led a coalition of 132 nations that secured the consensus adoption of a UN General Assembly resolution calling for the advisory opinion. The resolution sought to clarify states’ legal obligations under international law to protect the climate and environment from anthropogenic greenhouse gas emissions, and to determine the legal consequences for states whose actions or omissions cause significant harm to vulnerable nations and future generations. For the first time, the world court confirmed that countries failing to mitigate or adapt adequately could face legal accountability. Although not formally legally binding, ICJ advisory opinions strongly influence states, legislation, and courts by clarifying international law and shaping emerging customary norms. For African countries, which are least accountable for emissions but most severely affected, the ruling creates both opportunities to advance claims for justice and to secure international support, as well as responsibilities to strengthen domestic climate action.
This paper presents the dynamically evolving web of military agreements among EU member-states concluded by EU member-states outside the EU framework, identifying two distinct categories of such agreements: a) defence partnerships/agreements, which contain explicit mutual defence clauses, and b) defence industrial or operational cooperation schemes, focusing primarily on capability development, joint military structures or operational readiness. After briefly outlining why such agreements remain relevant and necessary in today’s security environment, the paper develops four future scenarios for EU defence cooperation:
The paper concludes with a set of policy recommendations, tailored to each potential trajectory.

IntroductionMilitary agreements represent the most tangible expression of security and defence cooperation. They translate (or transform) shared intent and objectives into structured and potentially legally binding commitments. In simpler terms, they embody trust, mutual benefit, and common concerns or threats. The coalitions of the willing on Ukraine indicate such common perceptions and stance, demonstrating some EU member-states’ willingness to mobilise beyond the existing Union’s cooperation schemes (e.g., the Common Security and Defence Policy missions and operations). They reveal that security and defence cooperation (even on the ground) is no longer optional, showing Europe’s strategic commitments as well as the political geography of European security. Nonetheless, the expanding landscape of treaties, pacts and memoranda also carries a paradox: the more these agreements multiply, the more complex and challenging coordination becomes. Thus, security and defence cooperation outside the EU framework consists of a dense web of interconnected elements, which are indirectly linked but lack a single central command and well-defined objectives.
This paper analyses the dense and complex landscape of military agreements concluded by EU member-states outside the EU framework. Hence, it deliberately excludes EU-level instruments, tools, and policies, such as the CSDP military missions and operations[1], the Permanent Structured Cooperation on Defence (PESCO)[2], the European Defence Fund (EDF)[3], the European Peace Facility (EPF)[4], or Military Mobility-related initiatives[5], as these are either treaty-based or closely linked to EU foreign policy actions. We also consciously leave aside schemes of cooperation established within or in the context of regional security organisations, like NATO and the OSCE.[6] Our focus remains on intergovernmental, bilateral or plurilateral, agreements in which national governments retain ownership of their (binding) commitments and political decisions, outside such institutional frameworks.
Our objective is to evaluate whether and how these agreements can contribute to a more coherent and credible EU defence. Drawing on our previous related work, this updated and expanded version posits that the proliferation of different types of agreements reflects both the EU’s cooperative instinct and its fragmentation. In particular, EU member-states have signed a multitude of military agreements, each reflecting specific political imperatives or regional security logics. The result is a dense web of cooperation frameworks that coexist, overlap and sometimes compete. To make sense of this complex reality, our analytical approach distinguishes between two kinds of military agreements, which differ in the level and depth of commitments undertaken by the signatories. In that respect, we identify:
The paper is organised into five chapters. The first introduces the conceptual and theoretical background, explaining why the EU’s liberal foundations and the member-states’ willingness to retain national sovereignty make such agreements possible and desirable. The second outlines the various types of agreements, categorised into two main groups. The third chapter explains why military agreements concluded by EU member-states outside the EU framework are necessary, considering the existing multifaceted constraints. The fourth chapter develops scenarios for the future of EU defence cooperation, based on the dense network of existing agreements. The fifth chapter offers policy recommendations aimed at improving the Union’s defence, coherence, and strategic autonomy.
Liberalism and the persisting need for military agreementsFor over seven decades, the European integration process has been guided by the liberal conviction that cooperation is both rational and necessary. Based on the liberal understanding, democracy and (economic) interdependence diminish the incentive for conflict. Understanding why EU member-states choose to cooperate, even in sensitive areas such as defence and outside the official framework of the Union, requires grounding this behaviour in the liberal school of thought of international relations, which emphasises interdependence, international law and shared values as foundations of peace.
Modern liberal theory mainly stems from three principal strands. The first, associated with John Locke, lies in the belief that individuals possess inalienable rights to life, liberty and property, and that states, as collective persons, inherit these rights in the form of political interdependence and territorial integrity. The second, developed by Adam Smith, Baron de Montesquieu and Joseph Schumpeter, articulates commercial liberalism, leading to liberal pacifism. The third, promoted by Immanuel Kant and Giuseppe Mazzini, advances a republican liberalism, which links democratic governance to international peace.
Doyle (1997) reformulated Kant’s ideas into the theory of a “separate peace” among liberal democracies: liberal states, constrained by representative institutions and guided by respect for rights, are peaceful with each other, though they may be in tension with non-liberal regimes. This assumption was first tested by Babst (1972), who evaluated Wright’s (1965) list of all major wars fought since 1500. His study indicated that “the existence of independent nations with elective governments greatly increases the chances for the maintenance of peace”. As classical liberals (e.g., Kant, Mazzini and Jeremy Bentham) anticipated, democratic institutions and greater interdependence would reduce uncertainty and increase predictability, thereby encouraging cooperation and international peace. Furthermore, based on Kant’s book “Perpetual Peace” and his definitive articles, Doyle (2006) explains that Kant “appears to have in mind a mutual nonaggression pact, perhaps a collective security agreement”.
When Kant’s triangle of peace is applied to the European project, one may understand why the Union’s evolution from an economic community to a political and security actor has been gradual yet persistent. Ikenberry (2001) underlines that in its most advanced manifestation, the international order includes an exercise of state power that is constrained and regulated by a framework of rules and institutions, and that states choose to participate in it motivated by self-interest, willingly exercising self-restraint. The EU epitomises this dynamic as it constitutes both a product and a guarantor of liberal internationalism. However, liberals often exhibit realist-like scepticism about the feasibility of fully surrendering national sovereignty, thus recognising the limitations of cooperation.
Considering the aforementioned, alongside the deteriorating geopolitical environment and the fragility of the international order, the proliferation of military agreements can be understood as a pragmatic expression of Europe’s liberal logic of cooperation, reconciled with the reality of state sovereignty. The EU’s defence architecture and its Treaties reveal a persistent reluctance among member-states to transfer full authority over defence policy to supranational institutions. The field of defence, which is deeply integrated into national identity, remains the ultimate bastion of sovereignty. Military agreements concluded by EU member-states outside the EU framework act as bridging instruments between the liberal aspiration for collective security and the member-states’ imperative to retain authority over the use of their armed forces.
This bridging is ever more relevant, considering the fragility of today’s international order becomes evident. The current strategic environment is characterised by aggression, hybridity, and great-power competition. Specifically, although Russia’s illegal annexation of Crimea in 2014 did not challenge the long-held assumption of enduring peace in Europe, the Russian invasion of Ukraine in 2022 did. It brought war and hostility back as methods of statecraft, exposing Europe’s vulnerabilities. Moreover, hybrid threats (including, but not limited to, cyber-attacks, threats and sabotage against critical infrastructure and disinformation campaigns) have blurred the lines between peace and war. As German Chancellor Friedrich Merz stated in September 2025, “we are not at war, but we are no longer at peace either”. On the international stage, the EU finds itself navigating a shifting geopolitical landscape. This is exemplified by the United States’ (US) shift of focus towards the homeland and the Western Hemisphere, prompting Europe to reassess its long-held reliance on the North Atlantic Treaty Organisation (NATO).
In this context, the warning expressed in August 2025 by the former Chief of the Defence Staff of France, General Thierry Burkhard, that “a weakened Europe may find itself tomorrow as a hunted animal” captures the sense of urgency. A united Europe that fails to coordinate its defence risks becoming a prey to its predators. To avoid such a devastating fate, Europe must confront the structural weaknesses that have long undermined its capacity for collective action. The EU continues to face persistent defence (capabilities) gaps, given the years-long military underspending and intra-EU legal and political constraints. Concerning readiness, the European (national) armed forces remain unevenly equipped and trained with disparities in deployable capabilities. At the same time, they continue to rely heavily on the US and NATO for specific high-end strategic enablers, further perplexing the complex EU-NATO relationship. Interoperability also remains limited, with different weapon systems and military doctrines often making joint action cumbersome at best.
These challenges in delivering the public good of security at the EU level are not technical. They are, in principle, political. They reflect divergent threat perceptions and strategic cultures across the Union. For some member-states, defence means strengthening (or sustaining in life) NATO. For others, it also includes deepening EU defence integration. This divergence has led to a proliferation of security and defence agreements, all reflecting different understandings of what European security (should) looks like. We are discussing these agreements in the following section.
Typology of military agreements: methodology and characteristicsMethodological approach and visualisation
Our categorisation of bilateral and plurilateral agreements concluded by EU member-states outside the EU framework in this paper is based solely on publicly available sources, including official treaty texts, national government press releases and other relevant documents. The visualisation of these agreements depicts the density of interactions and interconnections between member-states. For reasons of readability, when a stronger link already exists (e.g., a treaty with a mutual assistance or defence clause, which is shown in red), secondary agreements (e.g., defence industrial agreements) between the same states are excluded. The list is non-exhaustive and constitutes the product of a dynamic classification process, constantly monitored and updated.[7]

The first category includes the most formalised and politically significant layer of military cooperation in Europe. These are bilateral treaties that contain explicit references to mutual defence, assistance or solidarity clauses, usually framed around deterrence and shared threat perception. The dataset identifies five such key partnerships/agreements currently in force among EU member-states. These include the Franco-German Treaty of Aachen (2019), the Franco-Greek Defence Agreement (2021), the Franco-Italian Quirinal Treaty (2021), the Franco-Spanish Friendship Treaty (2023), and the Franco-Polish Treaty of Nancy (2025). Each contains clauses referring to mutual assistance in the event of an armed attack by a third country.

If collective defence treaties represent Europe’s political spine, industrial and operational cooperation schemes form its muscle and nervous system. These frameworks focus less on legal guarantees and more on capability development, joint military and command structures and interoperability. They bring substance to political commitments without, however, going the extra mile of providing explicit security guarantees. This category encompasses a wide variety of initiatives, some of which have multinational command structures and pools of shared personnel and/or resources. Others are more narrowly defined, focusing on specific capability domains, operational functions or vague commitments.
Key insights
France clearly stands out and naturally emerges as the central node of the bilateral military agreements with a defence clause, functioning as a strategic anchor. Its bilateral treaties combine political symbolism with operational cooperation, reaffirming Paris’ long-standing role as the EU’s key defence player.
These bilateral defence treaties are more than mere legal agreements; they often serve for the EU defence as strategic multipliers, enhancing the credibility and operational capabilities of the EU’s collective mutual assistance clause under Article 42.7 of the Treaty on European Union (TEU). In reality, they embody political will in action. The Franco-Greek agreement, for instance, is a clear expression of solidarity, complementing and supporting Article 42.7. The same principle applies to NATO’s Article 5, whose activation is not automatic, as it requires a unanimous political decision within the North Atlantic Council. In the case of Greece, the defence agreement also provides an additional layer of protection against Türkiye.
Box I: A French nuclear umbrella for European states? As doubts grow about the reliability of the US commitment to the security of the Old Continent, the idea of the French President, Emmanuel Macron, to extend France’s nuclear deterrent to other European states has gained attention. Nevertheless, serious obstacles remain. In the aforementioned agreements, France has not committed to expanding its nuclear deterrence to any of its partners. There are two main reasons for this. First, expanding the nuclear umbrella would strain France’s budget, which is already under pressure. Any decision to extend coverage to multiple member-states would require substantial additional investments (e.g., in delivery systems or in C2 platforms), even if a cost-sharing mechanism was in place, which is not. Second, French strategic culture is deeply rooted in nuclear independence. Extending the nuclear deterrent umbrella could imply either delegation or shared competence over nuclear use, and this constitutes a red line for the overwhelming majority of political forces in France.The second category of agreements concerns operational cooperation and defence industrial collaboration, encompassing a wide range of institutional, bilateral, minilateral and plurilateral arrangements that enhance Europe’s military interoperability, capability development and readiness. In contrast to collective defence treaties, which focus on security commitments, these frameworks primarily aim to develop and partially manage quasi-shared capabilities, coordinate operations and strengthen transnational defence-industrial cooperation.
A key example of operational cooperation is EUROCORPS, a multinational headquarters established in 1992. It provides a standing multinational command structure capable of planning and leading EU and NATO operations. Until present, EUROCORPS’ structures have been used for 8 missions abroad and 5 alert duties. It often serves as the Force Headquarters for EU Battlegroups. It does not constitute a permanent combat unit but a deployable high-readiness headquarters capable of commanding forces up to corps level.
Industrial cooperation mechanisms also form an integral part of this category. For instance, the Organisation Conjointe de Coopération en matière d’Armement (OCCAR), which was signed in 1998 and entered into force in 2001, aims to increase armaments cooperation, improve efficiency and reduce costs. As stated in its convention, OCCAR “shall coordinate, control and implement those armament programmes that are assigned to it by Member States and coordinate and promote joint activities for the future, thereby improving the effectiveness of project management in collaborative projects, in terms of cost, schedule and performance”. It manages major European projects, such as the A400M transport aircraft, the BOXER armoured vehicle and the FSAF surface-to-air anti-missile systems.
The category also entails a strong regional dimension. For example, the Central European Defence Cooperation (CEDC) exemplifies the growing importance of minilateral initiatives among like-minded and geographically close EU member-states. It serves as a security and defence platform, allowing participants to tackle “common regional challenges and threats” and initiate “projects among armed forces and capacity-building”. It has a clear focus on the civil-military dimension, as highlighted by the international military exercise “Cooperative Security”, which centred on managing the migration crisis and explored the role of armed forces in supporting civilian authorities during such contingencies.
Alongside structured initiatives, looser and more flexible forms of quasi-geopolitical cooperation also emerge. They function primarily as political consultation and coordination platforms rather than binding frameworks. A prominent example is the Weimar+ format, which constitutes an expansion of the Weimar Triangle between France, Germany and Poland. It reflects European states’ preference for flexible and issue-specific (i.e., Russia’s war of aggression against Ukraine) cooperation.
All in all, the second category illustrates the scope of this network, a dense and decentralised system linking smaller and medium-sized member-states across the EU. Unlike agreements with a defence clause, where France dominates, this operational network is polycentric. It demonstrates that even smaller member states participate and can play a role in European military cooperation. Cross-regional ties are evident, indicating that cooperation often may extend beyond simple geographic blocs. Nonetheless, cooperation usually follows geographical (e.g., BeNeSam, CEDC) or functional logic (e.g., EII, which brings together politically ambitious, willing and capable states under a French framework for expeditionary readiness).
The added value of bilateral/plurilateral agreements for EU member-statesIn today’s evolving security architecture, the space within which European defence cooperation can develop is not unlimited. It is conditioned on three key constraints that delimit the extent of EU cooperation and enhance the added value of bilateral and plurilateral schemes of cooperation: a) political and strategic constraints, rooted in the contradiction between national sovereignty and European integration, b) national constitutional and legal limitations, stemming from national laws and neutrality commitments, and c) institutional inefficiencies and ambiguities within the EU treaties. These constraints explain why EU member-states conclude military agreements outside the EU framework: they are not acts of defiance against the Union, but rather indicators of flexibility and adaptability. Hence, these agreements serve a dual purpose. First, they allow willing groups of member-states to act together more quickly and flexibly, avoiding the institutional bureaucratic procedures that often characterise EU-level processes. Second, they accommodate functional differentiation as not all member-states share the same threat perceptions or strategic priorities, allowing each state to collaborate without requiring a one-size-fits-all policy.
The enduring contradiction between sovereignty and integration
The most persistent cleavage shaping EU defence arises from the competing imperatives of national sovereignty and integration. National governments continue to consider security and defence as the hard core of statehood, which cannot be transferred to a supranational government. The deployment of armed forces, the use of force and nuclear deterrence are still perceived as sovereign prerogatives, often tied to national parliaments and domestic public opinion.
This deeply rooted attachment to national sovereignty contrasts with the integration logic of the European project that is built upon the premise that pooled sovereignty can yield positive collective outcomes (e.g., trade). However, defence remains a field where integration is politically and emotionally charged, and it usually collides with national political realities, such as divergent threat perceptions, strategic cultures, and domestic political and economic incentives. For instance, Warsaw may perceive Russia as an existential threat, whereas Madrid or Rome may view instability in the Sahel as their primary concern. A more extreme example would be the case in which member-states transfer the ultimate decision to go to war to Brussels. In addition, national leaders naturally tend to privilege formats that maintain visible national control, as one of their objectives is their reelection.
It is precisely because of these divergences that the treaties themselves reflect a cautious approach. Article 42.2 TEU explicitly states that “[t]he common security and defence policy shall include the progressive framing of a common Union defence policy. This will lead to a common defence, when the European Council, acting unanimously, so decides”. The wording of “progressive framing” and the requirement of unanimity are deliberate, as they acknowledge that the member-states do not yet share the same strategic culture (or levels of ambition). In essence, the treaties codify the political reality. As a result, defence cooperation in Europe tends to proceed horizontally, through intergovernmental agreements, rather than vertically through supranational mechanisms. These flexible formats preserve autonomy while enabling coordination.
Constitutional and legal constraints
Beyond politics, legal and constitutional constraints further narrow the scope for a common EU defence. Some member-states, notably Austria, Ireland and Malta, are bound by constitutional and/or policy commitments to neutrality. These obligations limit their participation in EU defence structures. For instance, Malta is hesitant to participate even in EU defence industrial initiatives. In fact, it does not participate in PESCO, nor do Maltese entities benefit from EDF funding. The neutrality of these countries illustrates how constitutional politics and national identity perceptions act as a brake on integration, insulating national decision-making from supranational influence. While differentiated integration has been advanced as a second-best pragmatic solution, allowing groups of member-states to deepen cooperation and coordinate their actions without requiring universal participation, this approach inevitably results in a fragmented EU defence landscape, according to which multiple security logics exist rather than one unified defence posture.
This tension becomes particularly evident when examining Article 42.7 TEU. While it constitutes (at least in theory) the EU’s mutual assistance clause, committing member-states to assist one another subject to armed aggression by a third state, legal constraints exist and have even been integrated into the text. In particular, the article explicitly refers to the fact that its implementation “shall not prejudice the specific character of the security and defence policy of certain Member States”. This constitutes a safeguard in the protection of the neutrality or non-alignment of certain member-states, granting them an exemption from any collective (quasi-)military obligation. In practice, this clause formalises the existence of institutional coexistence of solidarity and differentiation within the EU’s architecture, proving that a fully-fledged common defence remains incremental and politically sensitive.
Furthermore, fiscal frameworks can create another layer of constraint. Germany’s constitutional ‘debt brake’, in force until its reform in March 2025, exemplified how economic governance can indirectly shape defence policy. The rule limited Berlin’s ability to mobilise funds and prepare for the era in which we are currently living. This highlights that the domestic legal basis can paralyse strategic ambition and impede or delay collective EU defence efforts.
The ambiguity and inefficiency of the treaties
The EU treaties encourage the development of a common defence. However, in practice, this wording remains vague. It acknowledges the possibility of common defence but makes it conditional on unanimity (e.g., Article 42 TEU). The EU’s mutual assistance clause also carries legal ambiguity, particularly because of its unspecified scope and the lack of effective, clearly defined mechanisms for implementation. In other words, the clause’s pledge of solidarity lacks the institutional strength and concrete obligations needed to turn it into real action. The Niinistö report suggests further operationalising this clause, but it does not include a specific roadmap. Similarly, the Strategic Compass, while reaffirming the significance of the clause, fails to translate this commitment into actionable measures or concrete and specific examples.
The EU Battlegroups further illustrate this institutional paralysis. Although fully operational since 2007, they have never been deployed, mainly due to political hesitation and financial obstacles. In fact, unanimity and cost-sharing disputes repeatedly blocked their activation and their deployment on the ground.
At the same time, Article 41.2 TEU explicitly prohibits using the EU budget to fund “operations having military or defence implications”. This provision does not allow the Union to finance (from its budget) the activities that could render its defence credible, nor does it incentivise intra-EU cooperation. The Commission’s main defence-related initiatives have focused primarily on strengthening the European defence industry and supporting the development of dual-use infrastructure.
In a nutshell, this set of constraints infuses bilateral/plurilateral schemes of cooperation between EU member-states and constitutes the basis for alternative future scenarios regarding the future of EU defence collaboration.
Future ScenariosFigure III: Four future scenarios
The EU and its member-states stand at a strategic crossroads. The dense network of existing defence and military agreements demonstrates both the potential and the limits of the Union’s collective effort. Yet, as the security environment grows increasingly volatile, they must confront a fundamental question: what form should European defence take in the coming decade and what role should we envisage for the existing bilateral or plurilateral schemes of collaboration?
Four distinct, yet interconnected, scenarios can be envisaged for the evolution of Europe’s defence landscape. Each reflects a particular balance between sovereignty and integration, political ambition and institutional constraint and between regional pragmatism and supranational coherence. A combination of the four is also possible.
Scenario 1: Fragmentation and ad-hoc alliances
Codename: Archipelago of Alliances
Key players: National governments
In this scenario, the EU security architecture continues to evolve through bilateral and ad-hoc arrangements, without an overarching framework of coordination. EU member-states respond to threats in a decentralised manner, guided primarily by national threat perceptions, political preferences and historical ties. The absence of a unifying strategic centre leads to a proliferation of overlapping treaties, memoranda of understanding and initiatives. This fragmented model fosters a form of cooperation in which smaller or militarily weaker member-states align themselves with stronger partners for security guarantees. In this context, the EU serves as a platform for discussion and consultation, rather than for actual decision-making. Its institutional mechanisms (e.g., Article 42.7 TEU or the Rapid Deployment Capacity) remain underutilised or symbolically invoked.
As national governments become the key players, the Union’s strategic posture loses coherence. Europe moves towards a system reminiscent of the pre-integration era, notably an archipelago of alliances rather than a continent of collective defence.
Scenario 2: Regionalisation and the rise of defence clusters within the EU
Codename: Pragmatic adaptation to diversity
Key players: National governments
A second, more structured outcome would be the regionalisation of EU defence through the regional clustering of these bilateral/plurilateral agreements. In this scenario, geopolitical geography and shared security concerns drive the creation of sub-regional clusters with robust defence cooperation. Instead of a single European defence identity, the continent is witnessing the emergence of multiple, partially overlapping regional coalitions, led by EU member-states with the possible participation of like-minded third countries. France, as the EU’s biggest conventional military power and only nuclear power, would likely act as a cross-regional anchor, participating in multiple clusters to expand its strategic reach. In the Mediterranean, for example, the EuroMed-9, excluding Malta, could form the nucleus of a southern defence cluster, prioritising issues such as maritime security, migration-related instability and counterterrorism. This regional cluster will significantly contribute to the development of a more robust NATO strategy for the southern neighbourhood.
Regionalisation could enhance the EU’s responsiveness to local security dynamics and promote specialisation and pooling of resources. However, it risks fragmenting strategic coherence, as regional agendas diverge. Coordination across clusters would remain weak, and Brussels’ role would primarily be consultative. This scenario thus represents a pragmatic adaptation to diversity, which may be effective regionally but limited in forging a unified EU defence posture.
Key players in this model remain national governments, which could even establish region-based multinational commands to ensure interoperability and efficiency, without surrendering national control to supranational institutions.
Scenario 3: Nested integration and the EU’s defence mosaic
Codename: The Brussels nexus
Key players: European Commission and national governments
The third scenario envisions an EU that achieves defence integration through layering rather than centralisation. Here, existing bilateral/plurilateral military agreements are gradually clustered under an EU umbrella, creating a dense but more coordinated network of partnerships. In this institutional nesting, Brussels becomes a hub for connectivity not by commanding armies but by harmonising industrial, technological and operational cooperation. Under this scenario, the European Commission, working closely with the European Defence Agency (EDA), leads efforts to standardise procurement, strengthen the defence-industrial base, and foster interoperability among national forces, taking further the existing collaboration between member-states in the context of these agreements. Member-states retain control over operational decisions and deployments, but they recognise that industrial and technological sovereignty can only be achieved collectively. The EU framework would act as an integrative layer connecting national and regional initiatives.
Key actors in this scenario are the European Commission and national governments, which operate through the Council and the EDA. This model is institutionally feasible under current treaties, but its success would depend on sustained political will and financial commitment.
Scenario 4: Full operationalisation of Article 42.7 – Towards common defence
Codename: EU common defence
Key players: EU
The most ambitious scenario includes the full operationalisation of Article 42.7 TEU and the transformation of the EU into a quasi-defence alliance, relying on the acquis militaire created through these bilateral/plurilateral agreements. In this scenario, EU member-states agree binding mutual defence commitments at the EU level and establish a common protection umbrella guaranteeing the security of all member-states, building on the content of the most ambitious bilateral/plurilateral agreements. This scenario entails a unified command structure, shared funding mechanisms and common strategic culture. The EU effectively evolves into a European pillar within NATO. Regional clusters may persist, serving as platforms for niche capabilities (e.g., Arctic warfare, maritime surveillance). National sensitivities regarding command structures and budget would need to be reconciled. In this future, the EU will finally embody a common defence in substance, not only on paper, marking the end of fragmented security.
Scenario-based policy recommendationsAt this moment, Scenario 1 is what we experience in reality. There is an archipelago of alliances, where European ad-hoc alliances of diverse scope and depth multiply and fragmentation persists. The Defence Readiness Roadmap announced by the Commission and the High Representative on 16 October 2025 may pave the way for moving closer to Scenarios 2 and 3. In particular, forming capability coalitions between member-states to foster capability development and to broaden burden-sharing is the right way to go. In addition to these proposals, the following scenario-based policy recommendations aim to strengthen the EU’s defence collaboration and rationalise its cooperation frameworks.
From Scenario 1 to Scenario 2:
Foster regional defence clusters for niche capabilities: Recognising strategic diversity among EU member-states, the EU could encourage regionally focused defence clusters that complement the Union’s collective framework. For instance, the Nordic and Baltic member-states could specialise in Arctic and hybrid security, while the southern member-states could focus on maritime security. Such clusters should remain open and interoperable, functioning as pilot structures that can later be integrated into a broader EU framework. This resembles the logic underpinning PESCO projects, which should be further enhanced and utilised to create a conducive environment for Scenario 2.
From Scenarios 1 and 2 to Scenario 3:
Create a European Defence Agreements Register: A comprehensive mapping of existing bilateral/plurilateral agreements should be undertaken to identify overlaps, inefficiencies and redundancies. The main objective would be to understand the number and depth of existing schemes of cooperation, compare them, and attempt to consolidate and harmonise them. A single, regularly updated European Defence Agreements Register, coordinated by the European External Action Service and the respective national ministries, could serve as a monitoring tool that would facilitate closer coordination and prevent duplication. For example, if a plurilateral initiative already exists in a specific domain, two states could join it instead of establishing a bilateral agreement.
Invest in Defence Projects of Common Interest: These projects shall be universal and open to all EU member-states, with a 360-degree geographical coverage, meeting the most significant EU defence needs. In addition to the already announced projects (i.e., ANTIDRONE ETC), the creation of a “maritime shield” will signal the EU’s move to the Brussels nexus scenario.
Render bilateral/plurilateral agreements compatible with Article 42.7 TEU: Member-states shall prioritise the signing of new or the revision of existing bilateral/plurilateral military agreements, ensuring the inclusion of explicit defence clauses compatible with Article 42.7 TEU. Such clauses will entail clear legal obligations and well-defined procedures for invocation.
Moving to Scenario 4:
Operationalise Article 42.7 TEU: The EU should translate its mutual assistance clause and its principle of solidarity into practice. This requires strengthening the Military Planning and Conduct Capability (MPCC) and ensuring that the EU Rapid Deployment Capacity becomes a genuinely deployable tool. A clear roadmap of what happens after the invocation of the clause, an effective burden-sharing mechanism and command arrangements are indispensable. Formal links with NATO structures are vital, provided that they can only be established and function well if all NATO Allies recognise each and every EU member-state. Notably, the European Parliament, through a recent resolution, explicitly called on member-states to “activate Article 42(7) TEU where such gross aggressive actions amount to an armed attack or contribute to preparing an imminent attack” and urged both the EU and the member-states to establish “operational procedures and mechanisms” in case a country triggers this clause. In simple words, the resolution underscores the urgent need for clear and well-defined procedures. It is noteworthy that a first draft of this resolution went even further in its ambition, proposing that military support for member-states invoking Article 42.7 should be financed through the EPF and that any member-state opposing such use of the EPF would contravene “its duty of loyalty and solidarity”.
The four scenarios outlined in this paper illustrate the strategic crossroads at which the EU now stands. Whether it continues as an archipelago of ad hoc alliances, evolves into regional clusters, consolidates a Brussels-centred nexus, or advances towards a true common defence, each path reflects a distinct balance between current needs and the aforementioned existing constraints. In all four scenarios, the problem is not the absence of cooperation, but the failure to achieve implementing coherence. Fragmentation, as envisaged in Scenarios 1 and 2, may offer flexibility, but without a centre of gravity, the EU’s collective power diffuses. Pragmatically, Scenario 3 is the most feasible one to pursue at this moment, but its main challenge is to strike the right balance between the two levels (i.e., EU and bilateral/plurilateral) for providing the public good of security. Scenario 4 is the most ambitious one, paving the way for an EU army.
[1] EU military missions and operations allow member-states to deploy troops abroad for a wide range of tasks, as set out in the Petersberg Declaration adopted at the Ministerial Council of the Western European Union in June 1992.
[2] PESCO is a treaty-based framework for all member-states, excluding Malta, “to jointly plan, develop and invest in collaborative capability development and to enhance the operational readiness and contribution of armed forces”.
[3] The EDF constitutes the Commission’s main tool to support research and development in defence. It has a budget of approximately 7.3 billion EUR for the current Multiannual Financial Framework 2021-2027, with 2.7 billion EUR allocated for research and 5.3 billion EUR for capability development.
[4] The EPF is an off-budget tool aimed at enhancing the EU’s ability to promote peace and stability worldwide. It is structured in two pillars: a) operations, which finances the common costs of CSDP missions and operations with military or defence implications, and b) assistance measures, aiming to finance non-EU countries and international organisations to strengthen their military and defence capacity.
[5] The facilitation of the movement of military troops and assets has become a top priority for the EU, which has launched several strategic documents and initiatives related to military mobility, including but not limited to the Military Mobility Action Plan 2.0 or the Military Mobility PESCO project.
[6] For example, we do not take into consideration Air Policing missions in the framework of NATO.

Der Rat der Europäischen Zentralbank (EZB) hat in seiner heutigen Sitzung entschieden, den Leitzins unverändert zu belassen. Dazu eine Einschätzung von Marcel Fratzscher, Präsident des Deutschen Instituts für Wirtschaftsforschung (DIW Berlin):
Die EZB agiert weiterhin sehr vorsichtig und belässt den Leitzins daher unverändert. Sie sollte jedoch deutlicher als bisher signalisieren, dass sie im Zweifel bereit ist, die Zinsen weiter zu senken. Denn die Risiken für die Wirtschaft im Euroraum sind nach wie vor zahlreich und deuten auf eine weitere wirtschaftliche Abschwächung hin. Die Handelskonflikte, der Krieg in der Ukraine, die politische Lähmung in Ländern wie Frankreich sowie Finanzmarktrisiken dürften sich deutlich negativ auf die Konjunktur und damit auf die Inflation im Euroraum auswirken.
Auch die jüngsten Daten und Statistiken weisen auf eine schwächere wirtschaftliche Erholung hin als bislang erwartet. Die Finanzierungsbedingungen haben sich erneut verschlechtert, sodass der Leitzins der EZB für die Wirtschaft im Euroraum zu restriktiv ist.
Die Entscheidung der EZB, die Zinsen vorerst unverändert zu lassen, ist nachvollziehbar. Ein starkes Signal, dass sie die Risiken erkennt und bereit ist zu handeln, wäre jedoch hilfreich gewesen, um die Finanzierungsbedingungen zu stabilisieren und die Unsicherheit zu reduzieren.

The Greek 5×5 initiative aims to upgrade Greece’s regional role in the Eastern Mediterranean and extend a hand of friendship to Libya and Turkey. Until recently, Greece undertaking trilateral initiatives in the Eastern Mediterranean with Egypt and Cyprus, or Israel and Cyprus, allowed Turkey to claim that the purpose of such initiatives was to “encircle” Turkey, and that they took place without taking Turkey’s own vital interests in the Eastern Mediterranean into account. Nonetheless, it is considered unlikely that Turkey will participate without the issue of Turkish Cypriot representation in the talks being settled first. And since it is given that the occupied territories will not be represented, and as Turkey does not recognise the Republic of Cyprus, the success of the initiative will depend on finding a way for the Turkish Cypriots to be represented via bi-communal committees within the structures of the Republic of Cyprus. This effort may be the first sign that the parties intend to resume inter-communal talks for the resolution of the Cyprus Issue following Erhürman’s election.

The answer depends on the goal of the initiative. If it is a bone fide attempt to delimit the maritime zones of the countries involved, the difficulties in solving this equation continue to seem insurmountable. Convergence between the participants seems no more likely within the structure of a forum than without, as even with boundless optimism it is unlikely to expect that Turkey and Libya will move away significantly from the Turkish-Libyan Memorandum of Understanding and their claims in the Eastern Mediterranean. Additionally, before the difficult negotiations have even begun, Greece’s proposal has met a roadblock in the form of Turkish resistance to the participation of the Republic of Cyprus in the forum without an equivalent representative of the Turkish Cypriot community leadership.
If Greece’s goal, however, is to set the terms of a future discussion, before they are imposed by others, then initiative’s dynamic may be appraised under different terms. The approach of the current United States administration to critical international problems is at the same time fluid, as it often fluctuates, but also decisive. Thus, if the decision to resolve the issue is a fait accompli, against a backdrop of increased interest by US energy giants of operating in the region, the crucial question is how can the Greek proposal persuade the administration in Washington DC, and primarily President Trump himself, that delimitation can and must take place within the framework of a multilateral forum and international law, and not as a business deal governed by complementary economic and geopolitical gains.

Maritime zones, migration, energy, managing the environment, and civil protection—the issues around which the five-party initiative announced by the Greek Prime Minister is being planned—are matters that require multilateral cooperation, understanding and dialogue. Without them, all we get are parallel monologues and unilateral moves which reproduce disagreements and fail to create a climate of trust—and, through trust, cooperation. Greece is, in any case, a country that invests in multilateral cooperation and dialogue-based processes, primarily in the context of respect for international law and national sovereignty.
The regional coordination initiative is therefore a logical and ambitious endeavour aimed at fostering conditions favourable to stability.
However, it is clear both from the countries that seem likely to participate (Greece, Cyprus, Turkey, Egypt, Libya) and those that have not been announced as participants (Israel and Syria), that the undertaking will be a difficult one, and that multiple challenges will have to be faced which could, in a worst-case scenario, evolve into problems.
Consequently, if the momentum the initiative has built up is to be transformed into a positive impact, a clear framework is required, along with sincerity on the part of all the countries participating and faith in the logic of multilateral cooperation. The latter, in particular, cannot be taken for granted.
Finally, the role played by the EU and the US is another aspect that will have to be factored in.

Greece has rightly taken the initiative to advance a proposal concerning the Eastern Mediterranean—effectively reviving an earlier initiative (September 2020) originally put forward by the President of the European Council, which Athens had opposed at the time, arguably as a knee-jerk reaction to President Erdoğan’s endorsement of it. There remain, however, a number of obstacles to overcome and several contentious issues to resolve if the Forum on the Eastern Mediterranean is to materialize—among them, the participation of the Turkish Cypriot community, which Turkey will advocate for, and the question of Libya’s representation. From this perspective, the prospects of the initiative being realized in the near term appear limited.
Greece’s—albeit not yet fully developed—decision to reintroduce this proposal comes at a time of heightened activity in the Eastern Mediterranean: the recent ceasefire agreement in Gaza following a decisive intervention by the U.S. President; Turkey’s geopolitical upgrading; and Tufan Erhürman’s victory in the elections of the Turkish Cypriot community. These developments coincide with a shift in Greek–Turkish relations away from the “calm waters” of recent years toward stagnation or relative turbulence.
Against this backdrop, and given the possibility of President Trump becoming involved in Greek–Turkish relations and the Cyprus question, Greece has a vested interest in promoting initiatives that address key shared challenges—such as environmental protection, civil protection, and migration—facing the coastal states of the Eastern Mediterranean. Chief among these challenges is, of course, the delimitation of maritime zones. Such issues should be tackled within a regulatory framework capable of coordinating and supporting bilateral engagement through the timely notification of all parties and in full compliance with the provisions of UNCLOS (the United Nations Convention on the Law of the Sea). Within this framework, projects such as the Cyprus–Crete electricity interconnector could proceed more smoothly and with reduced risk of tension.
As for the next steps, it would be useful—indeed, perhaps essential—for the proposed five-state format to be expanded to include the European Union itself (the originator of the initial idea and a principal party to UNCLOS). The Forum could be also linked to certain institutional initiatives recently announced by the EU for the region, such as the “Pact for the Mediterranean”.

Background Many Sub-Saharan African countries have shifted from fiscally unsustainable free healthcare models to contributory national health insurance schemes, which rely on payments from informal sector workers. Yet, enrolling these workers remains a key barrier to achieving universal health coverage. Using the case of Kenya’s Afya Care free healthcare pilot, this paper investigates whether earlier exposure to free healthcare influences informal sector workers’ later decisions to enrol and contribute to the national health insurance scheme (NHIS). Methods We used nationally representative household survey data from 2018 and 2020, collected before and after the Afya Care pilot. The analysis focused on 6,900 informal sector workers, applying a quasi-experimental difference-in-differences approach to estimate the effect of exposure to the free healthcare pilot on subsequent NHIS enrollment. Results Before the pilot, no significant differences existed between treatment and control groups. After the intervention, NHIS enrollment was 10.5% higher in intervention counties (p < 0.001). Informal sector workers exposed to Afya Care were 65% more likely to enrol in the NHIS compared to those in control counties (odds ratio = 1.65; 95% CI = 0.96–2.83). Heterogeneity analysis showed that the policy’s impact was stronger among the least educated (30% higher enrollment) and the poorest workers (18% higher). Conclusions Exposure to the Afya Care pilot positively influenced informal sector workers’ willingness to join the NHIS and improved equity in enrollment. However, overall participation remains low. To expand coverage, the government should intensify information campaigns to raise awareness, extend subsidies to make premiums more affordable, and fully finance those unable to contribute. Strengthening these measures will be crucial for advancing Kenya’s progress toward universal health coverage.
