France and the United Kingdom continue to lead planning for a multinational reassurance force through the coalition of the willing, with a letter of intent signed in January 2026 outlining post-ceasefire roles in training, air and sea security, and support for Ukrainian forces. Recent statements from Macron reference potential contributions from France, Britain, and Turkey, with estimates around 15,000–20,000 troops focused on western Ukraine. However, all proposals remain conditional on a prior ceasefire agreement that has not materialized, and several NATO members including Poland and Italy have signaled reluctance to commit ground troops. Russia has rejected any such deployment as unacceptable. These factors, combined with the absence of formal national announcements committing forces, shape trader assessments of near-term developments.
