Britain and France are at the forefront of the effort by a group of European countries that are concerned US security priorities lie elsewhere.

U.S. Secretary of Defense Pete Hegseth unequivocally ruled out the involvement of American troops in a contingent that could enforce peace on the Russians after the end of the war in Ukraine. The burden of responsibility now rests on Europe.

U.S. president announces that talks with Russia’s leader on ending the war will start “immediately,” after his defense chief warns that Ukraine’s peace goals won’t be met.

Deterring Russia from re-invading Ukraine, once this war ends, could require 150,000 troops and American help with air cover, intelligence and missile defense, experts say.

The idea of guaranteeing Ukraine's security with troops provided by European countries is widely discussed. Ukrainians are evaluating whether Europe can deploy 100,000 soldiers and how such a number would impact border security.
