What is definition of cold war in idiomatic expression?

The term "Cold War" refers to a prolonged period of political tension and military rivalry, particularly between the United States and the Soviet Union, without direct armed conflict. In idiomatic expression, it can be likened to a "chilly standoff," where both sides maintain a façade of peace while engaging in espionage, Propaganda, and proxy wars, akin to a game of Chess with high stakes.
