U.S. proposes security guarantees for Ukraine, akin to NATO, to protect against attacks.

The U.S. has proposed offering Ukraine NATO-style security guarantees, short of full NATO membership, to ensure its defense. This proposal, discussed in calls between President Trump, Ukrainian President Zelensky, and European leaders, aims to provide a "non-NATO Article 5" clause, ensuring collective support if Ukraine is attacked. However, doubts exist about Russia's acceptance of such a plan, given Moscow's strong opposition to NATO expansion.
