Why was the relationship between the US and the Soviet Union call the cold war after the Postam conference in 1945?

The relationship between the US and the Soviet Union was termed the "Cold War" after the Potsdam Conference in 1945 due to the escalating tensions and ideological conflicts between the two superpowers, despite the absence of direct military confrontation. The conference highlighted deep divisions over post-war Europe, particularly regarding the future of Germany and Eastern Europe, leading to mutual distrust. This ideological struggle between capitalism and communism manifested in various forms, including political maneuvering, Propaganda, and proxy wars, establishing a prolonged period of geopolitical rivalry. The term "Cold War" reflects the lack of direct fighting while still indicating a fierce competition for global influence.
