US Secretary of War Pete Hegseth's decision to withdraw an infantry brigade from Romania has raised concerns about US troop pullback from Europe amid ongoing tensions with Russia. Experts warn that this uncoordinated retreat could undermine European security and embolden Russia, as NATO allies rush to rearm. Former US negotiator Kurt Volker criticized the decision as premature, emphasizing the need for coordination with European allies. The US is shifting focus towards Asia and Latin America, raising fears of a disengagement from European security.
