"The Manhattan project disproves the idea that "Super Weapons" were a as you put it a Hazy Possibility. "
Again, you show your ignorance of history. The further Hitler got into the war the more he gave up on the super weapons. He had functioning jet technology in his hands and instead of putting the resources into perfecting it decided to throw more of what was then conventional at his enemies.
The "nuclear bomb" Hitler is supposed to have made destroyed... 500 square meters, most of which was probably destroyed by the detonation charge, if the event ever happened at all. We weren't in any more danger from Hitler's nuclear capability than we were from Hussein's.
That said, what prevented both Hussein and Hitler from having a nuclear program was that they had to devote their limited resources to defense of their conventional efforts. Sure, had Hitler kept his agreements with the Soviets, hung onto his first few conquests, and then devoted himself to super weapons, it would have been horrific.
As it would have been with Hussein, who had been trying for nukes since the 80's. It's easy to sit back and poo poo any correlation, but in reality the two aren't very different. Had we allowed Hussein to take Saudi Arabia and a couple of other neighbors the way we allowed Hitler, who knows how the situation would have progressed.
Now, Hussein has done his little dance, so I guess you can Monday morning quarterback, huh? I bet a few million people in Europe during the 40's would have liked that ability. Had we simply contained Hitler, we would have seen a North Korea situation about 50 years early. Containment is foolish, but it's the go-to solution for people like the Col.
