**European allies, led by France and the UK, continue planning for a possible post-ceasefire “reassurance force” in Ukraine as part of the Coalition of the Willing.** In January 2026, UK Prime Minister Keir Starmer, French President Emmanuel Macron, and Ukrainian President Volodymyr Zelenskyy signed a declaration outlining potential multinational deployment after a peace agreement to support training, reconstruction, and deterrence. As of mid-October 2026, at least 1,500 personnel from the UK, France, Germany, and Poland are scheduled for November exercises in Poland rehearsing logistics, troop movements, and sustainment for a postwar scenario, with no decision yet on actual deployment inside Ukraine. Macron has promoted a multinational “Force de Réassurance” focused on key areas after hostilities end, drawing mixed responses—some nations express openness while others, including Italy and Poland, rule out or limit ground contributions. These steps reflect preparatory coordination rather than an immediate announcement, with any progress hinging on ceasefire developments and national parliamentary or alliance approvals.
