ABSTRACT: Weimar + was established in February 2025 to coordinate European support for Ukraine following a shift in United States’ (US) support for Ukraine under Trump 2.0. This viewpoint outlines the origins and objectives of Weimar+ and examines the relevance of the alliance as Europe recalibrates its approach towards security amid the ongoing Russia-Ukraine War.

The Foreign Ministers of Poland, Germany, France, Italy, Spain, the United Kingdom (UK) , and the Higher Representatives of the European Union (EU) for Foreign Affairs and Security Policy issued a joint statement reiterating their commitment to Ukraine in the face of the Russia-Ukraine war on 12 February 2025, under the name “Weimar+”. This happened in the wake of an official phone call between the US President Donald Trump, and Russian President Vladimir Putin where they had discussed the Russia-Ukraine war and a ceasefire._[1] The call led to immediate US–Russia ceasefire talks, beginning with ministerial-level negotiations in Riyadh that notably excluded European participation._[14] Against this backdrop, this viewpoint examines the origins, objectives, and challenges of the Weimar+ alliance.

BACKGROUND

Weimar+ is an alliance established to improve security and policy cooperation within Europe._[2] It reflects Europe’s effort to strengthen its strategic autonomy as a response to uncertainties of the US’s Ukraine policy. It is a coordination framework consisting of Germany, Poland, France, Italy, Spain, the UK, and the European Commission. Operating without the constraints of formal institutional structures, it generates shared Statements and Declarations that align with G7, NATO, and EU initiatives._[7][8] The meetings are attended by the Foreign Ministers of Member Countries and are frequently joined by Ukraine. The format remains adaptable, facilitating collaboration on military assistance, reconstruction efforts, and strategic communications._[8]  

The Weimar+ does not constitute an entirely new alliance, it is an extension of the Weimar Triangle. The Weimar Triangle, an alliance of France, Germany and Poland, was formed on 28th August 1991 to identify shared fundamental interests regarding Europe’s future, to extend cross-border cooperation and to support Poland’s transition away from Communist rule. _[3]  Having achieved its primary objective of facilitating Poland’s integration, the alliance subsequently receded in prominence and played a relatively limited role in broader European affairs. _[4]

But the pressures arising from the protracted Russia–Ukraine war  highlighted Europe’s need for broader and more unified strategic coordination. In light of this, a meeting in the “Weimar Triangle plus format” took place on 19th November 2024 in Warsaw attended by Foreign Ministers of Germany, France, Poland, Italy, Spain and the UK where support for Ukraine was upheld._[6]

The recalibration of the US Ukraine policy under Trump’s second administration further emphasized Europe’s need for a unified strategic framework_[5] Before Trump came into power earlier this year, European leaders believed that coordinated sanctions, sustained military aid, and Ukrainian battlefield resilience backed by strong transatlantic unity under President Biden would coerce Russia towards de-escalation _[5]  However, in February 2025 U.S. and Russia began direct ceasefire negotiations excluding Europe, starting with their first meeting on February 18 in Riyadh, which focused on partial ceasefire terms and reopening the Black Sea grain corridor. In March, Trump and Putin held further high-level discussions, during which Putin agreed to suspend strikes on Ukrainian energy infrastructure but refused a full ceasefire. Throughout these exchanges, European partners remained excluded from direct talks. Thus the Trump administration’s move towards bilateral negotiation with Russia excluding European participation, has led to the resurgence of the Weimar alliance and inclusion of other European leading actors._[10][11]The alliance’s first joint statement was issued in a meeting held on 12th February 2025, Paris.  Since then, two Weimar+ meetings have taken place: one in London on May 12th and another in Rome on June 12th.

OBJECTIVES

Given the previously outlined circumstances, Weimar+ sets out a clear set of objectives. One of the main objectives of the alliance is to reduce European reliance on the US by strengthening its capacity to act independently in security, defence, and foreign policy. This is important given Europe’s historical dependence on American military and deterrence capabilities within NATO, and the aforementioned shifts in U.S. policy towards Ukraine have only intensified the urgency for strategic autonomy. _[12]

Along with this, Weimar+ prioritises maintaining its influence over Ukraine-related negotiations to protect Europe’s immediate security interests and to ensure that any diplomatic outcomes uphold European norms and values. Without such involvement, there is a risk that outcomes of the negotiations, such as potential territorial concessions to Russia, could destabilise Eastern Europe and undermine principles of sovereignty, territorial integrity, and democracy and Europe’s global standing. Furthermore, the alliance is committed to providing sustained support for Ukraine “for as long as it takes,” encompassing military, economic, and political assistance._[9][10]

Underpinning these objectives is the broader intention to enhance European coordination, ensuring that member states can distribute responsibility and respond collectively and coherently to emerging security challenges. Nonetheless, despite these ambitions, significant obstacles remain that hinder Weimar+ from effectively translating its goals into outcomes.

CHALLENGES

Weimar+ faces significant challenges that limit its effectiveness. Due to the lack of formal institutionalisation of the alliance, no policy implementation or coordinated defence production has been possible. The practical implementation relies on EU frameworks, which are often slowed by bureaucratic hurdles. This means without legal authority, a permanent secretariat, or its own budget, its capacity to implement defence initiatives has been limited. So, all initiatives depend entirely on the commitment of national governments and due to diverging national interests among its members consensus-building has been difficult. For instance, France prioritises EU strategic autonomy, Poland emphasises strong ties with the US, and the UK remains partially detached from EU defence initiatives post-Brexit ._[13] In addition to this, efforts to advance strategic autonomy are complicated by the need to ensure complementarity with NATO, as member states remain cautious not to undermine transatlantic security guarantees while pursuing independent European capabilities. Overall, these factors suggest that while Weimar+ provides a platform for diplomatic alignment, its future impact will depend on the extent to which commitments are translated into sustained, collaborative initiatives.

CONCLUSION

The establishment of Weimar+ in February 2025 reflects Europe’s recognition of its strategic vulnerabilities because of the Russia–Ukraine war and shifting transatlantic dynamics under Trump 2.0. While it has emerged as a platform for Europe to assert agency and to coordinate military, economic, and political support for Ukraine, its ability to operationalise these objectives remains constrained by institutional limitations and diverging national priorities. Nonetheless, Weimar+ represents an important evolution in Europe’s pursuit of strategic autonomy by creating an agile, flexible format that can adapt to geopolitical uncertainties. Moving forward, its relevance will depend on the extent to which it can spur policy coordination in Europe and whether it can translate political declarations into coordinated defence production, sustained aid for Ukraine, and credible deterrence capabilities.
