Speaking at a defence summit in Brussels, Hegseth said the US would no longer "tolerate an imbalanced relationship" with its allies and called on Nato members to spend much more on defence. He also said it was "unrealistic" to expect Ukraine to return to its pre-2014 borders and downplayed the prospect of Ukraine joining Nato.

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.
