WASHINGTON DC – (MaraviPost): US President Donald Trump is once again threatening to leave NATO, this time over allies refusing to back the US-Israel war on Iran.
The move has sent shockwaves through the transatlantic alliance, with European leaders scrambling to assess the implications.
Trump’s latest salvo against NATO comes as no surprise, given his long-standing criticism of the alliance.
However, the timing is significant, coming as the US and Israel are engaged in a military campaign against Iran.
The US president has framed the Iran conflict as a test of NATO support, but European allies have largely rejected this approach, arguing the war falls outside the alliance’s mandate.
NATO Secretary-General Mark Rutte has emphasized that the alliance is a defensive organization, not a vehicle for supporting US military operations.
Trump’s threat to leave NATO has raised concerns about the future of the alliance and the security of Europe.

President Biden signed the 2024 National Defense Authorization Act (NDAA) in December 2023, which includes a bipartisan provision (Section 1250A) to strengthen U.S. commitment to NATO. The law prohibits any U.S. President from unilaterally withdrawing from NATO, requiring two-thirds Senate approval or an Act of Congress to exit, aiming to safeguard the alliance’s stability.
Key Reasons for the Legislation:
- Preventing Unilateral Withdrawal: The law specifically blocks a president from removing the U.S. from NATO without congressional approval, addressing concerns over threats to withdraw from the alliance.
- Ensuring Stability and Security: It acts as a check to preserve NATO’s stability against potential changes in U.S. administration policy, maintaining a united front against international security threats.
- Reinforcing Constitutional Balance: The measure reinforces the role of Congress in foreign policy and treaty obligations, ensuring that withdrawing from a major alliance is debated by lawmakers.
- Bipartisan Support: The amendment was introduced by Senators Tim Kaine (D-VA) and Marco Rubio (R-FL) to ensure that American foreign policy remains consistent and protected from arbitrary executive action.
While the 2020 Justice Department opinion suggested the President has exclusive authority to withdraw from treaties, this law creates a direct statutory requirement meant to hold any administration accountable in court if they try to bypass Congress.
While the US president can initiate the withdrawal process, he would need congressional approval to formally exit the alliance.
European leaders are keenly aware of the risks of a US withdrawal, with some already exploring alternative security arrangements.
The EU’s ReArm Europe initiative, aimed at mobilizing €800 billion for continental defense, is seen as a potential hedge against a US exit.
As the situation continues to unfold, one thing is clear: the transatlantic relationship is at a crossroads.
Will NATO survive the latest Trump ultimatum, or will it mark the beginning of the end for the alliance?
