The great imponderable of war is the population's willingness to keep waging it. I don't know what would have happened and neither does Wikipedia.
The anime Zipang brings up a more interesting point: had oil been discovered ten years earlier in Manchuria, would Japan have attacked the US and Dutch at all? Possibly yes: the question of “how do we defeat America?” eclipsed the more important “should we defeat America?” in Imperial Japan.
The policy of isolationism was very strong in the continental US. It's quite easy to imagine that the US gets bogged down in internal politics for years before stepping up.
What would you have said about England after Dunkirk? (With no hindsight allowed.)
It was a far closer fight than the United States and Japan. An invasion of the isles would have been impossible to pull off, and the war would almost certainly had gone the same way that it did - years of fighting over African colonies.
The battle of midway instead knocked out of all Japanese aircraft carriers. Unbeknownst to Japan, the United states was already pumping out several aircraft carriers per month and was also developing the nuclear bomb. The only possible change could have been surrendering to the Soviet union instead of United states. However, even that seems unlikely given the N bomb.
Dude named Oppenheimer begs to differ.
America still takes a lot of flack for demanding unconditional surrender which led us to drop two nukes on Japan. “The US could have just accepted peace terms with some concessions to Japan, then they wouldn’t have had to drop the bombs” is the line of argument.
All that would have happened was that the war in the pacific would have been extended by another six to twelve months.
Japan had constant oil shortages[0], had over a million men tied up in a land war in China, and its naval capacity was outproduced five-to-one by the United States. [1] The outcome of the War in the Pacific was inevitable, as of December 8th, 1941. [2]
