Answer:
Step-by-step explanation:
President Nixon pursued two important policies that both culminated in 1972. In February he visited Beijing, setting in motion normalization of relations with the People's Republic of China. In May, he traveled to the Soviet Union and signed agreements that contained the results of the first Strategic Arms Limitation Treaty talks (SALT I), and new negotiations were begun to extend further arms control and disarmament measures.
These developments marked the beginning of a period of “détente” in line with a general tendency among Americans to favor a lower profile in world affairs after the Vietnam War, which finally ended in 1975 with the last withdrawal of U.S. personnel.
