Paris Summit Clinches Draft 15-Year U.S.–Backed Security Guarantees for Post-War Ukraine

Big-power guarantees for small states rarely stick—Budapest Memorandum (1994) promised Ukraine security if it surrendered nukes, yet Moscow invaded in 2014/2022. The Paris plan tries to avoid that failure by coupling military back-stop, economic reconstruction and on-the-ground Western troops, recalling the 1955 Austrian State Treaty when foreign soldiers withdrew under neutral-status safeguards. It also echoes the 1995 Dayton accord in Bosnia, where outside peacekeepers enforced the deal for decades. Structurally, the move signals Europe’s bid to shed post-1949 dependence on U.S. force while still demanding a U.S. “back-stop”—a tension likely to define Euro-Atlantic security for decades. If ratified and—crucially—accepted by Russia, the arrangement could freeze Europe’s bloodiest war since 1945 and cement a new east-west military frontier; if it collapses, it will underscore the century-long pattern—from Versailles (1919) to Budapest (1994)—of ambitious paper guarantees that crumble once the ink dries.
