U.S. Warns North Korea Of Overwhelming Response

[Anomalocaris]

Hitler didn't have nukes?

Of course, he did try, but between his point-blank refusal to use "Jewish Physics" (read: everything from Einstein on) to putting several groups in charge of figuring it out, which ended in a combination of these groups trying to sabotage each others' efforts and trying to focus on other, more pressing wartime defense matters, it was destined to fail. It's a shame Los Alamos didn't figure that out until it was too late...

Actually, the US was already absolutely sure the Germans were both on the wrong theoretical track, and 2 years behind the US in material preparation by around June 1944.  It was already clear that there is no chance the Germans could either beat the us to the bomb, or build a bomb before its own military collapse.  By that time the real motivation for continuing with the manhattan project was to ensure postwar US geopolitical supremacy, not to beat the Germans.  This was the reason why the US embarked upon the expansion of Oakridge facility to produce fissile materials for several hundred bombs per year after learning the Germans won't have the bomb, but before trinity test in Alamogordo in 1945.

Incidentally,  Werner Heisenberg of the uncertainty principle fame, nobel prize winner, a founding father of quantum mechanics and one of the preeminent phycists of all time and not far short of Einstein himself is stature, was tapped by the nazis to head the theoretical calculations for the German atomic bomb effort. But he apparently made an extremely elementary conceptual error in his calculation, and massively exaggerated the amount of fissile material required to sustain a chain reaction. This exorbitant estimate of the uranium required to make one bomb made it seem unlikely the Germans could have successfully made the bomb within the foreseeable future, and led to reduction in the priority given by Hitler to the German atomic bomb project.  Many people argued that he intentionally made the error to sabotage the nazi bomb effort.

But this appears not to be so.  The US bugged his room after the war, and overheard him reacting with amazement at the news of Hiroshima, and going back to check his own calculation and eventually finding his own error.
