Role of the United States in the Vietnam War the presidency unopposed. With the installation of the Thieu and Ky government (the Second Republic), the U.S. had a pliable, stable, and semi-legitimate government in Saigon with which to deal. With the advent of "Rolling Thunder", American airbases and facilities needed to be constructed and manned for the aerial effort. On March 8, 1965, 3,500 United States Marines came ashore at Da Nang as the first wave of U.S. combat troops into South Vietnam, adding to the 25,000 U.S. military advisers already in place. The US Government deployment of ground forces to Da Nang had not been consulted with the
1964 in the Vietnam War and Vietnam's central highlands. Former President John F. Kennedy's brother, Robert Kennedy, said in an oral interview for the Kennedy Library that President Kennedy had "a strong, overwhelming reason for being in Vietnam and that we should win the war in Vietnam." Kennedy denied that any consideration had been given by the President to withdrawing from Vietnam. He equivocated on the introduction of U.S. ground troops into Vietnam, saying that "we'd face that when we came to it." Viet Cong commandos eluded detection and placed an explosive on the USS Card, an escort aircraft carrier of World War II vintage.
