In November 1961, Bundy advised Kennedy to send a division to fight in Vietnam, writing: "Laos was never really ours after 1954. South Vietnam is and want to be". In 1963, Bundy vetoed an attempt by another Harvard professor, Henry Kissinger, to join the Kennedy administration. Bundy knew Kissinger well and told Kennedy that he was a schemer who was not to trusted. In August 1963, when the diplomat Paul Kattenburg advised ending American support for South Vietnam, Bundy was extremely critical, arguing that American aid to South Vietnam was working as planned and accused Kattenburg of making an argument with no evidence. In October 1963, he agreed to the transfer of the CIA station chief, John Richardson, to help clear the way for a coup against President Diem. Just before the coup on 29 October 1963, Bundy wired the American ambassador in Saigon, Henry Cabot Lodge: "We do not accept as a basis for U.S. policy that we have no power to delay or discourage a coup". On the night of 1 November, Bundy stayed up all night, awaiting news of the coup, and reported to Kennedy in the morning that only the presidential guard had stayed loyal while the rest of the South Vietnamese Army had supported the coup. On 4 November, Bundy told the media that the United States would recognize the new government in Saigon. The same day he told to Kennedy that photographs of corpses of the Ngo brothers (Diệm and Nhu) might appear in the media showing their hands tied behind their backs and bullet holes through the back of their heads, joking that this was not his preferred way to commit suicide (it was initially announced that both Ngo brothers had committed suicide, through it was later admitted that they had been executed).
