Trump says he may withdraw U.S. from NATO. The law says he can't without Congress.

President Trump said he is considering withdrawing the United States from NATO, continuing his long-standing criticism of the alliance's burden-sharing arrangements. Trump has repeatedly complained that the U.S. bears too much responsibility for European defense costs relative to other member nations. However, U.S. law requires congressional approval for such a withdrawal, meaning Trump cannot unilaterally pull the country out of the 75-year-old alliance. NATO membership represents a cornerstone of post-World War II American foreign policy and collective security commitments to dozens of allied nations. The statement signals potential strain in transatlantic relations and would likely face significant resistance from Congress and American allies.
