Massive retaliation is a military strategy that involves responding to an enemy's aggressive action with a significant and overwhelming counterstrike, particularly through the use of nuclear weapons. This strategy was designed to deter potential aggressors by presenting the threat of catastrophic consequences for any acts of war, particularly during the tense period of the Cold War. The doctrine underscored the reliance on nuclear arsenals as a primary means of national defense and shaped the dynamics of international relations and military policies in the postwar era.
