Détente refers to a period of improved relations and decreased tension between the United States and the Soviet Union during the Cold War. It impacted détente policy by providing a framework for diplomatic efforts to reduce the risk of nuclear conflict and enhance cooperation between the superpowers.

SALT I and II:

The Strategic Arms Limitation Talks (SALT) I and II were agreements between the U.S. and the Soviet Union aimed at limiting the proliferation of nuclear weapons. SALT I, signed in 1972, and SALT II, signed in 1979, played a crucial role in the détente policy by establishing arms control measures and promoting stability in the nuclear balance between the two nations.
Nixon’s Visit to China:

President Richard Nixon's historic visit to China in 1972 was a significant diplomatic move that reshaped Cold War dynamics. By establishing diplomatic relations with China, Nixon sought to create a triangular balance of power and leverage this relationship to influence Soviet behavior. This strategic realignment influenced détente by introducing a new dimension to superpower relations.
Helsinki Accords:

The Helsinki Accords, signed in 1975, were a series of agreements aimed at improving relations between the Western and Eastern blocs. While not a direct product of détente, the accords contributed to the overall atmosphere of cooperation during the détente era by addressing issues such as human rights, economic cooperation, and territorial integrity, fostering dialogue between the U.S. and the Soviet Union.

rephrase like a 9th grader

Détente was a time when the United States and the Soviet Union became nicer to each other during the Cold War. This affected détente policy because it helped the two countries work together and avoid nuclear conflict. Two important agreements were SALT I and SALT II, which aimed to limit nuclear weapons. Another big thing was when President Nixon visited China to make friends and change the balance of power. And then there were the Helsinki Accords that focused on improving relations and talking about stuff like human rights.
