In February 1967, McCain received his sought-after promotion to full admiral (which became effective in May), and became
Commander-in-Chief, U.S. Naval Forces, Europe (CINCUSNAVEUR), stationed in
London. McCain's prominence made the downing of his son front-page news. McCain and his wife Roberta treated the news stoically, attending a dinner party in London without indicating anything was wrong, even though initial word indicated their son was unlikely to have survived the shoot-down. In April 1968, at the height of the Vietnam War, McCain was named by President Johnson as
Commander-in-Chief, Pacific Command (CINCPAC), effective in July 1968, stationed in
Honolulu and commander of all U.S. forces in the Vietnam theater. In an unprecedented move, Johnson had considered candidates from outside the Navy, including U.S. Army General
William Westmoreland, who was leaving as
commander of Military Assistance Command, Vietnam (MACV). However, the strong recommendation of Ellsworth Bunker, who had since become
U.S. Ambassador to South Vietnam, was key in Johnson's decision. McCain was a strong believer in the
domino theory, He became well known within the Pentagon and to the press for his fervent briefings on the "Chicom" menace, showing maps with bright-red claws or arrows extending from a bright-red China into much of the area he was responsible for. while to others, he was over-the-top and spoke longer than necessary. When the
Nixon Administration took office in January 1969, the secret
National Security Study Memorandum 1 collected views of top officials on the prospects for President
Richard Nixon's policy of
Vietnamization. McCain suffered a mild
stroke around this time, but was back at work a month later. Following an inspection tour of South Vietnam in December 1969, McCain remained very optimistic about the course of the war and the ability of South Vietnamese forces to carry greater burdens. McCain did not give much credence to the
anti-Vietnam War movement; in reaction to the popular slogan "
Make love, not war", he told a 1970 Naval Academy class that they were part of a fraternity "whose members are men enough to do both." McCain's views, which had the support of his subordinate, MACV commander General
Creighton Abrams, helped persuade Nixon to go ahead with the
Cambodian Incursion later that month. Kissinger subsequently told another admiral, "We have to be careful about having McCain around the president too much, because he fires up the president." Nevertheless, McCain was involved in the intense U.S. effort to prop up Cambodian leader Lon Nol, paying visits to
Phnom Penh to give him assurances and assess the state of the Cambodians. When Lon Nol suffered a stroke in early 1971, he recuperated at McCain's guesthouse in Honolulu. At the same time, a Military Equipment Delivery Team program was organized to supply military assistance to the Cambodian government. McCain gained control of this effort (instead of
Military Assistance Command, Vietnam), and to support a conflict that he proprietarily spoke of as "my war", made constant requests to the Pentagon for more arms and staff. He forced an Americanization of many logistics procedures within the Cambodian military. Lon Nol's gratitude towards McCain continued, including the gift of an elephant (soon named "Cincpachyderm") too large to transport on McCain's
DC-6. McCain was also very concerned about the North Vietnamese presence in Laos. He was a proponent of
Operation Lam Son 719, the February–March 1971 U.S.-assisted incursion into southeastern Laos by the South Vietnamese Army. He told Admiral
Thomas Moorer, chairman of the Joint Chiefs, that an offensive against the
Ho Chi Minh trail might compel Prince
Souvanna Phouma, prime minister of Laos, "to abandon the guise of neutrality and enter the war openly." The operation ended in failure. Each year while Jack McCain was CINCPAC, he paid a Christmastime visit to the American troops in South Vietnam serving closest to the
DMZ; he would stand alone and look north, to be as close to his son as he could get. During
Operation Linebacker, the resumed bombing of the north starting in April 1972, the targets included the Hanoi area. The daily orders were issued by McCain, knowing his imprisoned son was in the vicinity. In March 1972, the Nixon administration announced Admiral
Noel Gayler as McCain's successor as CINCPAC, despite McCain's unheeded request to Nixon to have his tour extended so that he could see the war to its conclusion. at the transfer of command ceremony in Honolulu that day, For the next two months, McCain served as special assistant to
Chief of Naval Operations Admiral
Elmo R. Zumwalt Jr. Kissinger would later characterize McCain's approach to the Vietnam War by saying, "He fought for the victory that his instinct and upbringing demanded and that political reality forbade." ==Retirement and death==
