The main purpose of this legislation is to require the President of the United States to formally announce the country's withdrawal from the North Atlantic Treaty Organization (NATO). The bill argues that NATO's original purpose has become irrelevant due to changes in the global security landscape, particularly after the end of the Cold War and the collapse of the Soviet Union. Key provisions of the legislation include a mandate for the President to notify NATO of the U.S. withdrawal within 30 days of the law being enacted.
