Dec. 10 (UPI) — U.S. Rep. Thomas Massie, a Republican serving a House district in Kentucky, introduced legislation for the United States to pull out of NATO.

Rep. Anna Paulina Luna, a Republican from Florida, posted on X that she would be a co-sponsor of the Not a Trusted Organization Act, or NATO Act. Utah Republican Mike Lee introduced the same legislation in the Senate earlier this year.

“NATO is a Cold War relic,” Massie said in a statement Tuesday. “We should withdraw from NATO and use that money to defend our own country, not socialist countries.

“NATO was created to counter the Soviet Union, which collapsed over 30 years ago. Since then, U.S. participation has cost taxpayers trillions of dollars and continues to risk U.S. involvement in foreign wars.”

He added: “Our Constitution did not authorize permanent foreign entanglements, something our Founding Fathers explicitly warned us against. America should not be the world’s security blanket – especially when wealthy countries refuse to pay for their own defense.”

NATO was founded in 1949 by 12 members as a military alliance involving European nations, as well as the U.S. and Canada in North America. There are now 32 members, with Finland joining in 2023 and Sweden in 2024.

The NATO Act would prevent the use of U.S. taxpayer funds for NATO’s common budgets, including its civil budget, military budget and the Security Investment Program.

Article 13 of the North Atlantic Treaty allows nations to opt out.

“After the Treaty has been in force for 20 years, any Party may cease to be a Party one year after its notice of denunciation has been given to the Government of the United States of America, which will inform the Governments of the other Parties of the deposit of each notice of denunciation,” the treaty reads.

During the last NATO summit in The Hague, the Netherlands, President Donald Trump told reporters he agrees with NATO’s Article 5 mutual defense treaty.

“I stand with it. That’s why I’m here,” Trump said. “If I didn’t stand with it, I wouldn’t be here.”

Article 5 was invoked for the first time after the 9/11 attacks in the United States, leading to NATO’s involvement in Afghanistan.

The Kentucky Republican, who calls himself a “fiscal hawk” and a “constitutional conservative,” has been at odds with Trump on several issues, including fiscal spending, foreign policy/war powers, government surveillance and transparency.

Trump has also been critical of NATO.

During his 2016 election campaign, Trump called the alliance “obsolete.”

He urged nations to spend at least 3.5% of gross domestic product on core defense needs by 2035.

In June, NATO allies agreed to a new defense spending guideline to invest 5% of GDP annually in defense and security by 2035.

Five nations were above 3% in 2024: Poland at 4.12%, Estonia at 3.43%, U.S. at 3.38%, Latvia at 3.15% and Greece at 3.08%. In last is Spain with 1.28% though Iceland has no armed forces and Sweden wasn’t listed.

Some Republican senators want stronger involvement in the alliance, including Joni Ernst of Iowa and Sen. Roger Wicker of Mississippi. Wicker is chairman of the Senate Armed Services Committee.

For passage, a House majority is needed, but 60 of 100 votes in the Senate to break the filibuster and then a majority vote. Trump could also veto the bill.
