President Donald Trump has stated he is considering withdrawing the US from NATO, but a 2023 law requires Senate approval with a two-thirds majority, setting up a potential legal and political showdown.
Trump's Recent Statements
- In interviews with The Telegraph and Reuters, Trump said he would "reconsider" US NATO membership and is "absolutely" considering withdrawal.
- He criticized European countries for not supporting the US in the Iran war and securing the Strait of Hormuz.
Congressional Law Blocks Unilateral Action
- A 2023 law, passed as part of the 2024 National Defense Authorization Act, requires the advice and consent of the Senate with a two-thirds majority to withdraw from NATO.
- The bill was co-sponsored by then-Sen. Marco Rubio (now Secretary of State) and Democratic Sen. Tim Kaine.
- This means even with all Republicans supporting withdrawal, at least 14 Democrats would need to join to meet the two-thirds threshold.
Bipartisan Senate Opposition
- Sen. Thom Tillis, top Republican on the Senate NATO Observer Group, stated it is "factually not true" that Trump can withdraw without Congress.
- Tillis warned that withdrawal could "poison the well" and make NATO "functionally defunct," emphasizing that American lives have been saved by NATO.
- Senate Minority Leader Chuck Schumer said the Senate will not vote to leave NATO, thanking Rubio for the law to prevent "clueless presidents" from acting on a whim.
Legal Battle Looms if Withdrawal Attempted
- According to a Congressional Research Service report, a unilateral withdrawal attempt could end up in court.
- Legal experts note that while presidents have historically withdrawn from treaties unilaterally, the 2023 statute explicitly requires congressional approval for NATO.
- Professor Curtis A. Bradley argues that the law is constitutional, as treaty-making requires congressional involvement, making the president's exclusive authority claim weak.
