Former U.S. President Donald Trump has reiterated threats to withdraw the United States from the NATO alliance, citing disagreements with European member states over their stance and involvement in the ongoing war between Israel and Iran. In a series of statements made during campaign rallies and on social media, Trump criticized allies for what he described as insufficient support and financial contributions.
The trans-Atlantic rift has deepened significantly since the outbreak of open hostilities between Israel and Iran in early 2025, following years of proxy conflict. European NATO members have largely called for de-escalation and diplomatic solutions, positions Trump has publicly condemned as weak.
NATO officials have not issued a formal response to Trump's latest comments. However, alliance diplomats have expressed concern that such rhetoric undermines collective security at a time of heightened global tension. The U.S. remains a critical member of the alliance, providing the bulk of its military capabilities.
Analysts note that while a U.S. withdrawal process would be complex and lengthy, sustained political pressure from a potential second Trump administration could severely damage the alliance's cohesion and operational effectiveness.
