This.
Also to hold off on invading Poland until Germany has at least a dozen of these functioning nuclear weapons.
I find it funny that he is considered the personification of pure evil in the west, while France had 60% of Africa enslaved, and Britain had the entire Middle East, North Africa, and all of India enslaved. (((Bolshevik))) Russia had ALREADY murdered tens of millions of white Christians and were threatening to take over nearly every country on earth. The US used a slightly different system of having the local rulers enslave their own people for America (or else, which is how most of South and Central America was operating when the war started.
But Hitler was the bad guy.

Separate the U-235 from the U-238. Have two or more pieces that smash together the U-235 with a small cannon configuration, and hold it together with a massive shell long enough to destroy a small city.
Bombs made from Plutonium-239 (which can ONLY be created in a nuclear reactor) are a little more complicated. They require a shell configuration, an "igniter" that produces neutrons, and various neutron reflectors to make the process work better.
"H-Bomb" is even more complicated. Starting with a Uranium / Plutonium bomb inside a large heavy canister filled with foam. The foam plasma compresses a canister of deuterium + tritium and/or lithium-deuteride which sprays neutrons back at the original reaction making it at least 10x stronger. Also, making the outer shell from U-235 will reflect the neutrons back (another boost) while the 235 itself adsorbs (some) neutrons and breaks apart releasing even more energy (yet another boost).
They're autistic Germans. Once they know it's possible they will figure it out fairly quickly, and probably won't even kill themselves like retards with a "Demon Core".
