Germany had MINI NUKES in 1945.

[Sgt. Boomer]

I remember seeing in a documentary that it was only one scientist, Werner Heisenberg, who sabotaged the nuc program. I just read on a couple of sites that Heisenberg’s post-war claim of sabotage might be a lie.

So the Norwegian resistance sinking a ferry carrying heavy water in Feb. 1944 might have been even more important than is usually thought.

Although, as the article stated: “It has also been pointed out that the United States employed thousands of scientists and invested billions of dollars in the Manhattan Project, while Germany\'s \"dirty bomb\" was allegedly the work of a few dozen top scientists who wanted to change the course of the war.”

Scary though that they came as close as they did.
