NATO defense chiefs are holding a virtual meeting to discuss security guarantees for Ukraine as part of efforts to end Russia's war on its neighbor

NATO's top military officials emerged from talks without a concrete plan to guarantee Ukraine's security – at least not one they were willing to discuss publicly.

U.S. and European military planners have begun exploring post-conflict security guarantees for Ukraine, U.S. officials and sources told Reuters on Tuesday, following President Donald Trump's pledge to help protect the country under any deal to end Russia's war.
