Détente and Its Collapse 1969–1985

Détente — the relaxation of Cold War tensions — represented the most sustained attempt to manage superpower relations cooperatively. From the late 1960s to the mid-1970s, the United States and the Soviet Union negotiated arms control agreements, expanded trade, and developed rules for their relationship. Yet by the early 1980s, détente had collapsed and the Cold War had intensified to levels not seen since the Cuban Missile Crisis. The key question is: was détente a genuine transformation of the Cold War, or merely a temporary pause driven by mutual convenience?

Key Definition: Détente (French for "relaxation") refers to the easing of strained relations between the USA and USSR, approximately 1969–1979. It encompassed arms control agreements, diplomatic summits, trade expansion, and the Helsinki Accords, but did not end ideological competition or the arms race.
