Answer:
Détente with the Soviet Union: Nixon pursued a policy of détente, which aimed to ease tensions and improve relations with the Soviet Union. The Strategic Arms Limitation Talks (SALT) treaties were negotiated during his presidency, which aimed to limit the growth of nuclear arsenals and reduce the risk of nuclear conflict.
Opening to China: Nixon's historic visit to China in 1972 and the subsequent normalization of diplomatic relations with the People's Republic of China marked a significant shift in U.S. foreign policy. This move not only contributed to peace in the region but also helped create a balance of power in Asia that eased Cold War tensions.
End of the Vietnam War: Although Nixon inherited the Vietnam War, he initiated a policy of Vietnamization, which aimed to transfer the responsibility for the war to the South Vietnamese government while reducing American troop levels. This policy eventually led to the end of the U.S. involvement in the Vietnam War, which was seen as a step toward peace.
Efforts in the Middle East: Nixon's administration played a role in facilitating ceasefire agreements during the Yom Kippur War in 1973. His administration's diplomatic efforts helped reduce tensions in the Middle East.
