Why the Nato alliance is not as likely to dissolve as Trump makes it seem

While President Trump has repeatedly questioned the value of NATO and suggested potential withdrawal, several deep-seated legal, institutional, and strategic factors make the alliance's dissolution unlikely as of April 2026.

 

1. Legal Barriers to Withdrawal

Congressional Restrictions: In 2023, the U.S. Congress passed a law specifically designed to prevent a president from unilaterally withdrawing from NATO.

Senate Approval Requirement: Under current statutes, any attempt to suspend, terminate, or withdraw from the North Atlantic Treaty requires either an Act of Congress or a two-thirds supermajority in the Senate.

Potential Constitutional Crisis: If a president tried to use executive authority to override these laws, it would likely trigger a massive court battle, with the Supreme Court acting as the final arbiter on whether treaty withdrawal is an exclusive executive power.

 

2. Radical Shift in European Burden-Sharing

One of Trump’s primary complaints—that allies do not pay their fair share—has been largely addressed by record-breaking increases in European defense spending:

Hitting Targets: As of 2025, all NATO allies reported defense spending that met or exceeded the 2% GDP target originally set in 2014.

New 5% Commitment: At the 2025 Summit in The Hague, allies committed to a new, even more ambitious goal: investing 5% of GDP annually in defense and security by 2035.

Spending Growth: In 2025 alone, European allies and Canada increased their defense spending by 20% compared to the previous year, reaching a total of $574 billion.

 

3. Institutional and Strategic Inertia

Deep Integration: NATO is more than just a treaty; it is a massive bureaucratic and military infrastructure including permanent command structures, satellite communications, and fuel pipelines that would take years to untangle.

Countering Adversaries: The alliance remains the primary vehicle for countering Russian and Chinese influence. Abandoning it would, according to bipartisan congressional warnings, "embolden adversaries" and erode decades of American global leadership.

Mutual Benefits: Despite the rhetoric, the U.S. gains significant strategic depth and intelligence capabilities from its presence in Europe, which remains critical for managing global crises.

4. "Hollow" vs. Formal Withdrawal

Experts note that while a formal dissolution is difficult, a president can "hollow out" the alliance without legally leaving it. This could involve:

Withdrawing U.S. troops from Europe.

Removing Americans from the NATO command structure.

Refusing to deploy forces under Article 5 (collective defense), which is entirely at the president's discretion as commander-in-chief.
