Upon his election, President Richard Nixon tapped Kissinger as his national security advisor, a position held from January 20, 1969, to November 3, 1975. On September 23, 1973, Kissinger took on the dual role of secretary of state, making him the first person to hold both positions at once. He was also the first secretary of state born on foreign soil.
Kissinger quickly established himself as a diplomatic heavyweight, landing on magazine covers and making international headlines for his brand of "realpolitiks," based on practical, rather than moral, decisions. “The state is a fragile organization,” he wrote in 2015’s World Order, “and the statesman does not have the moral right to risk its survival on ethical restraint.”
Kissinger also engaged with China in 1972, setting the stage for Nixon’s pivotal visit to the communist nation to meet with Chairman Mao Zedong—the first time a sitting U.S. president had visited mainland China and seen as a Cold War turning point.
While visiting Middle East capitals to help enemies reach disengagement agreements in the 1970s, Kissinger spearheaded what came to be known as "shuttle diplomacy," which contributed to OPEC to lifting its U.S. oil embargo. Kissinger is also noted for helping negotiate a truce between Israel and Arab states following the 1973 Arab-Israeli War, also known as the Yom Kippur War, and resuming diplomacy between America and Egypt.
According to the U.S. Department of State, while secretary of state, Kissinger made 213 foreign country visits, once traveling to 17 countries in 18 days, and spending 33 consecutive days in the Middle East in 1973, negotiating talks between Syria and Israel.
While Kissinger controversially hid the 1969 bombings of Cambodia and Laos from Congress that escalated the Vietnam War, 68 meetings with North Vietnam's Le Duc Tho, some of which were secret, eventually led to the Paris Peace accords. These accords ended direct U.S. involvement in the Vietnam War. Kissinger and Le Duc Tho were controversially awarded the Nobel Peace Prize in 1973 for their roles in the negotiation, although only Kissinger accepted it. The accord's provisions were then subsequently broken by both North and South Vietnamese forces with no official response from the United States. According to the Washington Post, Kissinger tried to return his Nobel.
Controversies Swirl During Ford Administration
In the Gallup Poll's annual list of men most admired by Americans, Kissinger ranked first in both 1973 and 1974, beating out both Nixon and President Gerald Ford, who took office August 9, 1974 following Nixon's resignation after the Watergate scandal. Ford kept Kissinger on as secretary of state, though he ended his role of national security adviser in 1975, and Kissinger focused much of his work again on the Middle East, negotiating the 1975 Sinai Accord between Egypt and Israel. But, coupled with controversies in Angola and Chile, an end to the Paris Peace accords and increasing tensions with the Soviets, his reputation was tarnished.
He served his final day as secretary of state on January 20, 1977, when Jimmy Carter took the presidential oath of office.
