As soon as Germany had been defeated. The UK, USA Russia and France had already agreed on how to divide Europe, and the USSR declared war on Japan (the USSR and Japan hadn't fought in WWII until this point) and 'liberated' China. Many commentators say that the two atomic bombs dropped on Japan were the first warning shots in the cold war.
The WWII wartime alliance (known as the Grand Alliance) between the U.S. and the Soviet Union began to unravel for multiple reasons, including that the U.S. was upset that Joseph Stalin, the Soviet leader, had signed a nonaggression pact with Germany in 1939. Additionally, Stalin blamed the Allies for not invading German-occupied Europe earlier than 1944.

A significant cause of Soviet mistrust of the Western Allies during World War II was the delay in opening a second front in Europe, which the Soviets believed would alleviate pressure on their forces fighting the Nazis. Additionally, the Western Allies' negotiations with the Soviet Union, particularly regarding post-war plans and territorial divisions, often lacked transparency, fueling suspicions. The ideological differences between the capitalist West and the communist Soviet Union further exacerbated these tensions, leading to a pervasive sense of distrust throughout the war.
