Can NATO Survive a US Withdrawal? Trump’s Threats Explained (2026)

The future of NATO hangs in the balance as Donald Trump's disdain for the alliance and its members continues to test its resilience. With the recent decision by NATO allies to refrain from joining Trump's war on Iran, a critical question arises: Can NATO survive, especially if the US decides to pull out?

The Fractured Alliance

Trump's anger over defense spending and his threats towards Denmark's territory, Greenland, have left NATO on edge for years. The current Middle East crisis has only exacerbated these tensions, with analysts suggesting that the alliance may never fully recover from this strain.

A Potential Breakup?

While Trump cannot unilaterally withdraw the US from NATO, he has the power to significantly undermine the alliance. The US has no obligation to aid allies in the event of an attack, and Trump could move American troops out of Europe, close military bases, and cease coordination with allies. These actions would severely damage the credibility of NATO as an effective defense mechanism.

Europe's Defense Challenges

Russia's invasion of Ukraine highlighted Europe's reliance on the US for defense capabilities. European allies have increased their defense spending, but they still face significant challenges in areas such as deep strike capabilities, intelligence, and satellite technology. Filling these gaps will require substantial investment and time, with estimates suggesting a decade or more of effort and a trillion-dollar price tag.

A European NATO?

Some experts believe that a European-led NATO is possible, arguing that the alliance has become a structure for military cooperation among European countries. Minna Alander, an analyst, suggests that European members have an incentive to maintain NATO, even in a different form, to counter potential Russian aggression. However, the timeline for this transformation is uncertain, with estimates ranging from 2027 to 2029 for when Russia may pose a direct threat to NATO territory.

The US and NATO

The debate surrounding NATO often overlooks its broader purpose beyond protecting Europe from Russia. NATO was a network of alliances formed during the Cold War, and its invocation of Article 5 following the 9/11 attacks demonstrated its value to the US. European bases were crucial staging grounds during the Iran war, even if countries publicly distanced themselves. Europe's lack of investment in defense has created a strong dependence on the US, but NATO serves a broader strategic interest beyond European borders.

As the world navigates these complex geopolitical dynamics, the future of NATO remains uncertain. The alliance's ability to adapt and withstand the pressures of a changing global landscape will be crucial to its survival and effectiveness.
