Grand Alliance

Britain, the USA and the USSR had cooperated in the Grand Alliance because they shared enemies in the Second World War. Cooperation did not mean that they shared the same beliefs or plans for peace. As Germany’s defeat approached in 1945, the question changed from how to win the war to who would shape the post-war world.

The Grand Alliance brought Britain, the USA and the Soviet Union together against Nazi Germany during the Second World War. Germany’s invasion of the Soviet Union in June 1941 made cooperation with Britain essential for Stalin. The USA entered the war in December 1941 after Japan attacked Pearl Harbour.

During the Second World War, Britain, the USA and the USSR worked together in the Grand Alliance to defeat Nazi Germany. Their cooperation did not mean that they shared the same beliefs. Fighting a common enemy gave them a powerful reason to set their differences aside.
