Who was to blame for the Cold War?

Examine the factors contributing to the onset of the Cold War, including the disintegration of the US-Soviet alliance post-1945, the USSR's control over Eastern Europe by 1948, the US response to Soviet expansion, the implications of the Berlin Blockade, and assess whether the United States or the USSR bears greater responsibility for initiating the Cold War. Key topics include the 1945 summit meetings, the Soviet expansion in Eastern Europe, the occupation of Germany, the Berlin Blockade, NATO, and the Warsaw Pact.
