President Nixon wrote a letter to President Thieu of South Vietnam which was delivered in Saigon by military adviser Alexander Haig. Nixon said he was "irrevocably" committed to sign the peace agreement and said he would do so "alone, if necessary."

Nixon pledged to "react strongly in the event the agreement is violated" by North Vietnam and to continue aid to South Vietnam if Thieu cooperated."

North Vietnam celebrated the signing of the Paris Peace Accords as a victory. "The Vietnamese revolution has achieved several important gains, but the struggle of our people must continue to consolidate those victories [to] build a peaceful, unified, independent, democratic, and strong Vietnam."

The plenum of the Communist Party in North Vietnam recommended the escalation of political activity and military action in South Vietnam "in response to Saigon's flagrant and continued violations of the cease fire."

The War Powers Resolution of 1973 (50 U.S.C. 1541–1548) was a United States Congress joint resolution providing that the President can send U.S. armed forces into action abroad only by authorization of Congress or if the United States is already under attack or serious threat. The War Powers Resolution requires the president to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30 day withdrawal period, without an authorization of the use of military force or a declaration of war. The resolution was passed by two-thirds of Congress, overriding a presidential veto.
