Which term describes the easing of Cold War tensions in the 1970s?

The term that describes the easing of Cold War tensions in the 1970s is "détente." This period was characterized by a relaxation of the confrontational stance traditionally held by the United States and the Soviet Union. During détente, both superpowers engaged in diplomacy aimed at reducing the risk of nuclear war, exemplified by treaties such as the Strategic Arms Limitation Talks (SALT). It marked a shift toward more cooperative international relations, including trade agreements and cultural exchanges, as both nations sought to manage their rivalry more peacefully.

Understanding the context of détente helps clarify its significance as a historical moment when the threat of direct conflict was temporarily reduced through dialogue and negotiation. It stands in contrast to the other options, which represent different aspects of international relations that do not pertain to this specific easing of tensions.
