Repeal

The administration of President Richard Nixon, which took office in January 1969, initially opposed repeal, warning of "consequences for Southeast Asia go beyond the war in Vietnam". In 1970 the administration began to shift its stance. It asserted that its conduct of operations in Southeast Asia was based not on the resolution but was a constitutional exercise of the president's authority, as commander in chief of U.S. military forces, to take necessary steps to protect American troops as they were gradually withdrawn (the U.S. had begun withdrawing its forces from Vietnam in 1969 under a policy known as " Vietnamization ").
