President Donald Trump is scheduled to meet with Mark Rutte, the Secretary-General of NATO, which has sparked discussions about the potential for the United States to withdraw from the military alliance. This meeting comes in the wake of Trump's dissatisfaction with NATO's support during the Iran conflict, where he has taken military action against Iran. The North Atlantic Treaty, established in 1949, allows any member nation, including the US, to exit after providing a one-year notice. However, the process requires notifying the US government, which then informs other NATO members. Importantly, while the president can initiate the withdrawal process, US law mandates that any exit from NATO must be approved by Congress, specifically requiring a two-thirds Senate majority or an act of Congress. Thus, while Trump could not unilaterally decide to leave NATO, he retains authority over troop deployments, which could impact NATO's military capabilities.
