What war turned the war over to the allies?

The turning point of World War II for the Allies can largely be attributed to the Battle of Stalingrad, which took place from 1942 to 1943. The Soviet Union's victory marked a significant shift on the Eastern Front, halting the German advance and beginning a series of successful Soviet offensives. Additionally, the Allied landings in Normandy (D-Day) in June 1944 opened a Western Front, further stretching German resources and leading to their eventual defeat. These events collectively turned the tide in favor of the Allies.
