Why did the Nazis have such a technological advantage in Wolfenstein: The New Order?

In Wolfenstein: The New Order, the premise is that Nazi Germany won WWII, contrary to normal history. I understood that this was due to vastly superior tech, but why did their tech outpace the rest of the world so much?
I have played through the game already, and I can't really remember them explaining this directly. The big issue is that the game starts after the Nazis have basically already won the war: the first mission is a last-ditch effort to maybe win the war, but the missions after that are all set after the war has ended, in a resistance-style storyline. There is not much explanation that i remember as to why the Nazi tech is so much better.
