In my opinion there is two main points that allowed the Allies to win the war in the European theater. The first one is when the Russians were able to stall the Germans at Stalingrad. If the Russians would have lost Stalingrad Germany would've had little resistance on their march to Moscow. The second happened when Allied forces were able to halt the last major offensive of the Germans in the Ardennes Mountains of Belgium all so known as the Battle of the Bulge.

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.
The Allied landings of D-Day were the most decisive strategic event in turning the tide in favour of the Allies.
The Battle of Midway, fought from June 4 to June 7, 1942, was the critical engagement that turned the tide of war in the Pacific in favor of the Allies. U.S. forces successfully ambushed the Japanese fleet, sinking four of their aircraft carriers while losing only one of their own, the USS Yorktown. This decisive victory significantly weakened Japan's naval strength and marked the beginning of a series of successful Allied offensives in the Pacific theater.

Second Battle of El Alamein turned the tide of the war in North Africa for the Allies. It was the first Allied Victory in two years and proved British commander Field Marshal Montgomery's reputation.
