The absence of the U.S. in World War II would have had profound consequences for the global landscape. Without American intervention, the Allied forces might have struggled to mount the necessary military and logistical efforts to counter the Axis powers. The war in Europe could have been prolonged significantly, potentially ending in a negotiated peace that left Nazi Germany with a strong foothold. In the Pacific, Japan might have solidified its dominance over Asia, creating an imperial bloc that reshaped the global balance of power.

Domestically, the U.S. might have maintained its isolationist stance, delaying its emergence as a superpower. The industrial boom and technological advancements driven by wartime demands might not have occurred, slowing the nation's economic growth. Additionally, the lack of involvement in the war could have influenced America's position in the Cold War, altering its relationship with the Soviet Union and its leadership role in establishing post-war international organizations like the United Nations.
