Can the President Withdraw the U.S. from NATO?

Despite occasional political rhetoric suggesting otherwise, the idea that a U.S. president could unilaterally pull the country out of NATO is more complex than it appears. While past administrations have occasionally raised the possibility of reevaluating America’s commitments to the alliance, the legal reality has shifted in recent years.

As of 2026, the president cannot simply withdraw the United States from the North Atlantic Treaty without significant congressional involvement. This is due to Section 1250A of the 2024 National Defense Authorization Act (NDAA), which explicitly restricts presidential authority in this area. Under this provision, any attempt to suspend, terminate, or denounce the treaty must be done either with the advice and consent of the Senate—requiring a two-thirds majority of those present—or through a specific act of Congress.

This legislative safeguard was designed to prevent rash or unilateral decisions that could undermine decades of transatlantic security cooperation. It reflects a growing recognition in Washington that alliances like NATO are too strategically vital to be subject to the whims of a single leader. The move also echoes historical precedents where Congress has sought to check executive power in foreign policy, particularly on matters of war and treaty obligations.

While the president remains a key player in shaping foreign policy, this restriction underscores the constitutional balance of power. NATO membership, once entered into, isn’t something that can be undone by executive fiat. It requires broad political consensus—a reminder that in American democracy, even the most powerful office has its limits.

So, while the question of NATO withdrawal may surface during political debates, the answer is now firmly rooted in law: the president doesn’t have that power alone.
