Seemingly from the inception of the Soviet Union all the way to present day, the Soviet Union and every version of it that followed has been at odds with the United States. Communism and capitalism are functionally antithetical, and since the USSR and the United States respectively embody each system, it makes sense that there would be natural animosity. It seems that the only time they weren’t blatantly antagonistic towards each other was during World War Two.
Starting with the Twenty Year Mutual Assistance Agreement and the Lend Lease Agreement, in which the US agreed to supply the Soviet Union with supplies and other aid if they agreed to defend the US against foreign aggression, the two countries entered a period of tentative camaraderie. Movies were made in which Americans and Russians worked together and rallies were organized in an effort to reconcile each to the other.
The height of the American-Soviet cooperation was probably when Stalin, Roosevelt, and Churchill met at the Yalta Conference to discuss what would become of Europe and of international relations once the war had ended. Obviously cooperation between the parties would not last long once the war ended, but for a time, the two future superpowers were actually allies.
