<human>:  I want to learn about the history of World War II. At what points did the Allies gain an advantage over the Axis powers?
<bot>: Initially the Allies were at a disadvantage to the Axis powers because the Axis powers had greater resources and experienced military forces. However, the Allies gradually gained an advantage after the Battle of Stalingrad in 1943, when the Soviet Union decisively defeated Germany. The Western Allies also began to gain a strategic advantage in the Pacific after the Battle of Midway in 1942. In addition, their naval and air superiority, as well as their industrial strength, also began to give the Allies a significant advantage throughout the war. Ultimately, the Axis powers were defeated in 1945.
