U.S. Defense Secretary Pete Hegseth's attention-grabbing overseas debut may have irritated some key Republicans and alienated allies in Europe, where his statements on Ukraine and NATO went down like a lead balloon.

Hegseth urged NATO allies to bolster their defense spending from 2% to 5% of their GDP, noting that the U.S. is attempting to "revive the warrior ethos" as well.

U.S. Secretary of Defense Pete Hegseth has called for NATO’s European members to increase their role in the defense of Europe as the United States focuses on defending the alliance’s Pacific flank. It is a move that he says will likely require European allies to significantly increase defense spending from 2% of GDP to about 5% of GDP.
