If you are going to fall down that rabbit hole make sure you fall down the part about the history of Deuterium in Norway during World War II.

During the Nazi occupation they were trying to produce Deuterium for their nuclear weapons program in Norway and the Norwegian resistance staged an incredible series of sabotage events to stop them.

"The Winter Fortress" by Neil Bascomb is a really great read about this. The Nazis probably still wouldn't have gotten their first but we all owe something to the Norwegians for their role in making sure they didn't get there at all.
