British Prime Minister Keir Starmer urged European leaders to strengthen their borders and support Ukraine, outlining a plan to end Russia’s war. Speaking at a summit in London, Starmer emphasized the need for collective responsibility and what he called a coalition of the willing to defend Ukraine. He pledged to maintain aid, economic pressure on Russia, and military support while ensuring Ukraine’s sovereignty in any peace deal. Starmer urged European leaders to take greater responsibility for their security after Trump criticized Zelenskyy and cast doubt on U.S. support for Ukraine.
