Détente refers to the period of relaxed tensions and improved relations between the United States and the Soviet Union during the Cold War, primarily in the 1970s. This era was marked by diplomatic negotiations, arms control agreements, and increased trade, aiming to reduce the risk of nuclear conflict. Key events of détente included the signing of the Strategic Arms Limitation Talks (SALT) treaties, which limited the number of nuclear weapons each superpower could possess. The policy was a response to the high-stakes rivalry and sought to promote stability and cooperation, although it faced challenges and ultimately declined in the late 1970s.
