>A "Manhattan Project" would be building some shocking new technology that didn't previously exist.

I think that both Germany and USSR were not in the least shocked ... just the USA had the resources to finish it.

Well, USSR did finish, just 4 years later.

Maybe it was because we had all those immigrants working on it (e.g. Albert Einstein, Hans Bethe, and John von Neumann)!

		There's a whole regiment of immigrants who worked on the Manhattan project, as we all know. We also know that the USSR obtained much of their knowledge on how to build the bomb through espionage.
