At a Paris meeting of Ukraine’s partners, the United States and European allies backed the idea of binding security guarantees meant to deter any renewed Russian attack after a ceasefire. The discussions included proposals for monitoring and enforcement mechanisms, with an emphasis on support that does not require U.S. troops on the ground.

France and the United Kingdom signaled they are prepared to deploy forces after a ceasefire to help stabilize Ukraine, while other countries expressed varying levels of willingness. Russia, meanwhile, has opposed NATO-linked military presence in Ukraine, leaving a major obstacle to any durable settlement.
