How did the Allies finally win the war?

By February 1943, Soviet defenders had finally defeated the massive German offensive against Stalingrad, turning the tide of the war in Europe. After gargantuan sacrifices in fighting that had lasted for eighteen months, the Red Army forced Hitler’s Wehrmacht to turn back toward the west. In the Pacific, the Allies had halted the expansion of the Japanese empire but now had the deadly task of dislodging Japanese defenders from the outposts they still occupied. Allied military planners devised a strategy to annihilate Axis resistance by taking advantage of America’s industrial superiority. A secret plan to develop a superbomb harnessing atomic power came to fruition too late to use against Germany. But when the atomic bomb devastated the cities of Hiroshima and Nagasaki, Japan finally surrendered, canceling the planned assault on the Japanese homeland by hundreds of thousands of American soldiers and sailors and their allies.
