Not to take away from your thesis (I agree that this was likely a very solveable issue, and after all they didn't need to fly across an ocean), but even Little Boy was 9700 lbs, which was nearly 2000 lbs/25% more than the He 111's capacity even with rocket assisted takeoff. So it is indeed easy to overlook that simply having something to deliver the massive things was no small feat

> Up to 3,600 kilograms (7,900 lb) could be carried externally. External bomb racks blocked the internal bomb bay. Carrying bombs externally increased weight and drag and impaired the aircraft's performance significantly. Carrying the maximum load usually required rocket-assisted take-off.

You're right about Little Boy, i'd misread kilos as pounds, oops, and sorry. That said, my main points stand:

First, that lack of financial resources wasn't an obstacle to the Bomb. Hitler had his government spend absurdly colossal sums on other and ultimately useless things mainly because of his stubborn fixations (real surprise, that) and even with the scientific brain drain due to Nazi persection of jews and dissidents of all stripes, enough sharp minds remained in Germany to pull it off I believe, but only if the whole concept had been taken seriously enough, early enough and with good planning and funding.

Secondly: Assuming they'd actually developed the bomb, delivery would have been a very solveable problem at that point for stopping a western Allied invasion dead in its tracks.

Stopping the vast soviet army would have been a different matter entirely, especially if they only developed the atom bomb later in the war. I'm not entirely sure about even a nuclear weapon being enough to put a brake on that level of thirst for revenge, combined with so much military force for applying said revenge.

In broad strokes I agree, but my overall point was exactly about this facet, which I excerpt:

> even with the scientific brain drain due to Nazi persection of jews and dissidents of all stripes

My point was precisely about that brain drain, in particular the dismissal of "Jewish Physics" (see https://en.wikipedia.org/wiki/Deutsche_Physik), which drove the atomic physicists right into America's open arms

So to watch the US destroy its seed corn with its own xenophobic brain drain is particularly ironic
