Answer 2

The war started to turn against Germany in 1942, with the Soviet victory at the Battle of Stalingrad. This marked a major turning point as it was the first major defeat for German forces. Additionally, the entry of the United States into the war in December 1941 and the subsequent Allied offensives in North Africa and Italy in 1943 further weakened Germany's position.
