Answer:
Detente
Step-by-step explanation:
Detente: Détente is a French term, meaning a relaxing or easing; the term has been used in international politics since the early 1970s. Generally, it may be applied to any international situation where previously hostile nations not involved in an open war de-escalate tensions through diplomacy and confidence-building measures. However, it is primarily used in reference to the general reduction in the tension between the Soviet Union and the United States and a thawing of the Cold War, occurring from the late 1960s until the start of the 1980s.
