Answer: Midway. From Dec. 1941 to Summer 1942, America had been fighting a defensive war against Japan (ever since Pearl Harbor, America was fighting to keep its territories in the Pacific until island-hopping started.)

America and its allies could go on the offensive because Midway greatly damaged the Japanese fleet.
