In 1969, Nixon withdrew 6,000 Americans from Vietnam, and it continued for three years. In 1971, only 6,000 Americans left in Vietnam.
In 1970, Nixon sent troops to Cambodia with television and the infiltration of anti-war. The campus of Kent State University in Ohio and Jackson State University in Mississippi were sent in troops to suppress the anti-war protest. Four students died in the revolts.
Daniel in the Pentagon paper talked about the mobility of the wars and the dishonesty of the American government in the procedures: soldiers disobeyed to the orders, lynchings, using drugs. Nixon's response: 66% of the Americans want to get out of the war, continuing FBI and CIA surveillance. The peace accord was singed in Paris on January 21, 1973. Nixon ends out the war without peace and honor before the South Vietnam collapses.
In March 1975, North Vietnam lunched for an offensive operation on attacking South Vietnam.
In April, the next month, the North Vietnam seize Saigon as the US and the South Vietnam troops official flee.
Results: 57 billion spent, 38,000 dead, 500,000 injured, POEs, MIAs, social unrest and social problems continued.
By the Saturday night massacre, a suspicion on Nixon grew.
The court asked Nixon to release some of the tapes; Nixon claimed his executive power and refused to give up the tapes, at first.
But, later, Nixon released some of the translated tapes, and the public was shocked at the languages Nixon used, tong precisivly.
Under the court's request, Nixon released three tapes; and, one of the tapes is found to have an 18-minutes gap. Nixon's secretary, Rose Marywood denied the deliverance. Tapes are the smoking gun: the evidence proved that Nixon knew of the covering-up from the begin.
The Congress reasserts its authority. The congress established Presidential Campaign Activities, publicly financing for the Presidential Campaign. Congress established a permanent committee to check and balance the power of FBI and CIA surveillance. Public distrust and Syndicism grew. Wilber Mill, Wiley Hay, Edward, and Kennedy's scandals.
