On 10 April 2025, NATO hosted the last of a series of meetings of the so-called ‘coalition of the willing’ (Gray & Van Overstraeten, 2025). The initiative, spearheaded by British Prime Minister Keir Starmer and supported by French President Emmanuel Macron, was first introduced at the London Summit on Ukraine in March (Davies, 2025). Bringing together defence ministers from 30 nations, including Canada and Australia but excluding the United States (US), the coalition aims to establish a ‘reassurance force’ for Ukraine in the event of a ceasefire with Russia (Melkozerova, 2025). The group seeks a credible and lasting European-made peace, reducing the chances of a future invasion from Russia even without US security guarantees promised to the war-torn country. In the words of the British Defence Secretary, the aim is to “put Ukraine in the strongest possible position, to protect its sovereignty and deter further Russian aggression” (Gray & Van Overstraeten, 2025). The urgency of the project has grown amid declining U.S. support under the Trump administration, which has pushed Europe to assume greater responsibility for its own security as Washington pivots its strategic focus toward the Pacific.
