BRUSSELS — U.S. Defense Secretary Pete Hegseth will send his deputy to a meeting of NATO defense ministers next month, according to a U.S. official and a European diplomat, a decision likely to raise further questions about Washington’s dedication to the transatlantic alliance.

NATO’s 32 defense chiefs will gather Feb. 12 for the first ministerial-level meeting since U.S. President Donald Trump brought the alliance to the brink of implosion by repeatedly suggesting he could seize Greenland from Denmark by force. 

But Hegseth, who prompted outrage at the same meeting last year by delivering a blistering attack on Europeans for not spending enough on their defense, is not expected to participate, said the two officials, both of whom were granted anonymity to speak freely. 

Instead, Elbridge Colby, the undersecretary for defense policy, is set to attend in his place, the diplomat and official said, a decision that is still subject to change. Colby is the third-highest-ranking civilian defense official at the Pentagon and a close ally of U.S. Vice President JD Vance.

The U.S. Department of Defense didn’t immediately respond to a request for comment by POLITICO.

Colby, nicknamed “Bridge,” is seen as a hardliner on Europe inside the Pentagon and is a staunch supporter of an isolationist U.S. foreign policy that advocates a less active American role — especially militarily — worldwide. He is also responsible for drafting plans on an expected drawdown of U.S. troops from Europe, which has faced repeated delays. 

Colby was responsible for crafting the new American defense strategy, published last week, which downgraded Europe and said Washington would instead “prioritize” defending the U.S. homeland and China.

Before publication, the document underwent deep revisions by U.S. Treasury Secretary Scott Bessent, who pushed for changes to the China section in light of trade talks between Beijing and Washington. Bessent’s input also toned down the China language in the White House’s National Security Strategy, released late last year.  

The defense strategy also makes clear that in Europe “allies will take the lead” against threats that are “less severe” for the United States — a euphemism for Russia.

It’s not the first time Hegseth has skipped a NATO meeting. But it marks the second time in a row a top U.S. official has missed a high-level gathering after Secretary of State Marco Rubio similarly dispatched his deputy to a meeting of NATO foreign ministers last month.

Oana Lungescu, a former NATO spokesperson, said the move “risks sending a further signal that the U.S. isn’t listening as closely as it should to the concerns of its allies, especially after Marco Rubio skipped the last meeting.”

“Having said that, there is also an upside,” said Lungescu, who now works as a senior fellow at the Royal United Services Institute think tank, “in that Elbridge Colby … is best placed to explain [the new U.S. defense strategy’s] intent and implications, and to hear the views of allies.”
