How might the world be different if the attack on pearl harbor never existed?

Answer 1

Prior to the U.S. entering WW II on the side of Great Britain and the Allies, there was a lot of opposition to getting involved in the 'European war'. This political attitude was known as 'isolationism'. The idea was that America had enough problems of its own, as we were still in the midst of the Great Depression. It was the view of many that getting entangled in a foreign war would only add to our problems. And after all, no one had attacked the United States.

President Franklin Roosevelt wanted very much to come to the aid of our British friends, who were under direct attack by the Germans. English cities were being bombed almost every night by the ferocious German Air Force. Roosevelt did not have enough political support to outright send troops and weapons into the war. He was able, however, to get Congress to pass a bill, known as the Lend-Lease Act. This law enabled Roosevelt to send munitions, planes, weapons, food, and medical supplies to Britain. Many of these supplies were destroyed in transit as German U-Boats (submarines) sunk many supply ships on their way to Britain.

As it turned out, Japan chose December 7th, 1941 to attack Pearl Harbor in the U.S. territory of Hawaii, destroying much of the U.S. Navy Pacific Fleet and killing thousands of American servicemen. This largely unprovoked attack quickly changed the majority political opinions of the American people. Finally, president Roosevelt had the political support he needed to enter the war in Europe and open a pacific front to drive the Japanese out of the Pacific. The entire American nation was put on a wartime footing, and all efforts went toward winning the war.

Fortunately for the Allies, the U.S. was the first nation to develop atomic bombs and deploy them on enemy territory. The speed at which the U.S. developed atomic capabilities was a direct result of the commitment to win the war. Without that strong national objective, the U.S. atomic project may have been delayed for many years.

If Japan had not attacked the U.S. when it did, the outcome of WW II may have been very different. It was discovered after the war that Germany was very close to developing their own atomic bombs. The U.S. entry into the war and our bombing of German factories, railways, and military bases slowed down their atomic bomb project significantly. If Germany had been able to develop and detonate atomic bombs in Great Britain and the Soviet Union, it is entirely possible that the Allies would have had to sue for peace or face total annihilation.

Of course, this is only speculation. Many other factors may have come into play that could have changed to outcome of the war.

Answer 2

United States would have never entered the Second World War

Answer

We would have entered WWII later and defeated Japan, but taken longer with Germany (maybe)

Answer 3

Hiroshima wouldn't have been destroyed and many innocent people would still be alive. Trade with countries, and alliances would be completely different. Someone else may have used a Nuke to settle a problem not fearing the US's impulse Nuke attack.

Answer 4

The answer here can only be speculation. As Japan wanted total control of Eastern Asia, the US Military force in the Philippines would have to be eliminated. This most likely have caused the US to take military action against Japan. The results were exactly what did happen. Japan was defeated and disarmed.

Answer 5

then the united states might not have officially gotten involved in ww2
