As secretary-general, Rutte does not have the authority to "personally expel" a country from the alliance. While he leads the alliance, according to NATO's website, "authority for taking decisions is invested only in the member governments themselves."

A post on X claims that Secretary General of the North American Treaty Organization (NATO) Mark Rutte said he will expel the U.S. from the organization if President-Elect Trump “surrenders Ukraine to Putin.

It's not the first time since Trump's reelection that Rutte has stressed that Russia's invasion of Ukraine is a security matter for the U.S. — and the world. Last week, he said North Korea's involvement threatens the Indo-Pacific region.

Former U.K. Prime Minister Boris Johnson said the country may have to send troops to Ukraine if Trump cuts U.S. military aid and funding.
