European leaders are racing to shore up the continent's security framework as the Trump administration systematically withdraws from its decades-long commitment to European defense, leaving allies to confront Russian aggression and regional instability with diminishing American support.
German Chancellor Friedrich Merz has proposed that Ukraine become an "associate member" of the European Union before becoming a fully fledged member state, in a move he says would allow Ukraine to request assistance from other EU countries against a Russian attack and create a "substantial security guarantee." The proposal comes as NATO foreign affairs ministers meet in Sweden for a two-day summit focused on the Trump administration's plans to withdraw guarantees of support for European security architecture, even in wartime, and on the depletion of the alliance's critical weapons stocks because of the ongoing war in Iran.
A Lifeline for Ukraine
Merz wrote in a letter to EU leaders that it was "obvious" the accession process could not be completed shortly because of "countless hurdles" and the political complexities of ratification in member states, and said it was time to move ahead with "innovative solutions." Under the proposal, Ukraine would gain access to the European Council, the European Commission and the European Parliament without voting rights or a dedicated portfolio, and could tap certain EU-funded programmes on a "step-by-step" basis. A "snap-back mechanism" would freeze the status if Kyiv backtracked on fundamental rights, rule of law or structural reforms.
Merz said the proposal would be a "strong political signal" for Ukraine and its citizens in their fight against Russian aggression and would help facilitate peace talks as part of a negotiated peace solution. He said the proposal should not derail accession processes for Moldova and the Western Balkans, and said they should also benefit from "privileged access" to the single market and "closer ties" with Brussels. Austria, the Czech Republic, Italy, Slovakia and Slovenia have circulated their own proposal for a sectoral integration of all candidate countries.
The pitch coincides with the departure of Hungarian Prime Minister Viktor Orbán, the prime opponent of Ukraine's accession. Orbán's successor, Péter Magyar, has signalled readiness to lift the veto and let Kyiv open the first cluster of negotiations, known as "fundamentals," after meeting Volodymyr Zelenskyy to discuss the Hungarian minority in Ukraine. Budapest and Kyiv launched formal consultations on the matter this week. If enough progress is achieved, Ukraine could open the first cluster by the time the 27 leaders meet in Brussels on 18-19 June, and the other five clusters could be opened throughout the remainder of 2026.
America's Strategic Retreat
The Trump administration plans to incrementally withdraw the US from European security, and sources at NATO said the plan does change the US contribution to NATO in the event of crisis or conflict. NATO Secretary General Mark Rutte said ahead of the meeting in Brussels on Wednesday, "This has been expected," adding, "We know that adjustments will take place, the US has to pivot toward, for example, Asia." He said, "this will take place over time, in a structured way," and insisted "the US will stay involved in Europe." The adjustment is being worked out within the NATO force model.
Donald Trump had abruptly announced he was pulling 5,000 soldiers from Germany after a feud with German Chancellor Friedrich Merz over the US-Israeli war with Iran, and Trump took offence when Merz criticised the war as ill-conceived and said White House negotiators were being "humiliated" by the regime in Tehran. Instead of cutting 5,000 troops from Germany, Trump cancelled the deployment of 4,000 soldiers already en route to Poland.
Weapons Shortages Loom
US Secretary of State Marco Rubio is expected to join the meeting and emphasize the need for greater defence industrial output. NATO allies buy complex weapons from the US through the Prioritised Ukraine Requirements List. Euronews said that if the attrition rate continues, Europe could face shortages of munitions deliveries for the Ukrainian army. Mark Rutte said, "The question is no longer whether we need to do more. The question is how quickly allies can turn commitments into capabilities."
The ministerial meeting is a staging post for the annual NATO leaders' summit in Ankara in July. Ministers will decide whether to extend a formal invite to Ukrainian President Volodymyr Zelenskyy, who attended part of last year's summit at The Hague at the invitation of the King of the Netherlands. The year before, at the summit in Washington DC, Zelenskyy received a full invite under the Biden administration.
Merz said he wanted an agreement soon and a dedicated task force to work out the details.
Why This Matters:
The simultaneous American withdrawal from European security commitments and Europe's scramble to integrate Ukraine reveals the fragility of the post-Cold War security order that has protected millions from conflict. For Ukrainian civilians enduring Russian aggression, the associate membership proposal offers tangible hope for protection and reconstruction assistance, while the depletion of weapons stocks threatens their ability to defend their communities. The Trump administration's abrupt troop cancellations—triggered by diplomatic disputes rather than strategic necessity—demonstrate how erratic policy-making undermines collective security arrangements that have kept the peace for generations. European workers and families now face the prospect of shouldering defense costs that were previously shared across the Atlantic, even as weapons shortages could leave vulnerable populations exposed. The outcome of next month's Brussels summit and the Ankara meeting in two months will determine whether democratic institutions can forge a multilateral response to authoritarian aggression, or whether great power politics will fracture the cooperative frameworks that have protected human rights and regional stability.
