How are European leaders responding to the U.S.-Russia talks on Ukraine?

European leaders are expressing serious concerns about the emerging relationship between the U.S. and Russia. The French Prime Minister specifically condemned what he called an "unthinkable alliance between Putin and Trump" that is effectively marginalizing Europe on its own soil. This reaction highlights growing anxiety among European leaders about being sidelined in negotiations affecting European security, particularly as President Trump has controversially placed blame on Ukraine for the war rather than Russia.
