Would Germany have won WWII if Japan didn bomb the U.S.?
Because everyone is arguing that the USSR and Britain could handle Germany simply with American arms, I will attempt to argue that yes, Germany would have won the war. Assume that Japan not only didn’t attack America, but also left American sphere of influence in Asia untouched, and that America would not declare war on the Axis until, for my argument 1945. Before WWII, the American army was not a force, it was something like the 17th in the world (don’t quote me on the number.) America would have less incentive to develop the weapons that it did during WWII. Germany had been developing and continued to develop throughout the war. Assuming that Germany had an extra three year head start, it would have beaten America to all of the technologies, the Nuclear Bomb, Long range jet bombers and fighters (look at the ME-262 deployed at the end of the war,) and mid to long range missiles. I don’t think the Allies could defeat that foe.
