Welcome to the Board. Please don't be discouraged by the responses you are going to get, honestly including mine. A lot of us started out with impossible scenarios.
After invading France he then went ahead with operation sea lion and invaded Britain while at the same time sabotaging any attempts by the Americans to create the atom bomb while recruiting scientists to create the ultimate weapon.
First, Operation Sealion is a TERRIBLE idea. The Germans were planning to use river barges for troop transports, which would have been slaughtered by the Royal Navy. In short, it would have been a disaster which would have resulted in all ten divisions (all infantry) either dead in the Channel, or forced to surrender after their resupply is cut off (since all the ports combined in the landing area could give them some 10% of their needed supplies even IF captured intact).
Meanwhile, they can't really sabotage American efforts, amongst other reasons because the US hasn't started it in 1940. Meanwhile Germany's own efforts were so incorrect that they had concluded an atomic bomb was impossible after a couple of years, which actually was the BETTER option, since they also thought the reaction would be self-limiting when it...wouldn't. If they had managed to move ahead the resulting radiation leak would have killed the entire scientific team, whatever Party officials were there to watch, and then irradiated central Germany.
Then in 1942 invade the soviet union waiting a year to re group and re supply and use the hatred of Moscow to their advantage by recruiting Ukrainian's to fight alongside them to then take Moscow quickly with the co operation with Japan fighting in the eastern front. After taking the USSR then provide independence for the Ukrainians by installing a puppet government to make it seem like they have independence and by that time the first atom bomb has been tested.
Nope. First, the Nazis couldn't cooperate with Ukraine. They had to sieze the food supplies of the people in order to keep their armies moving, and people who are starting to starve are notoriously unlikely to be happy with the invader. In addition, Nazi doctrine calls for the murder of most of the Ukrainian population, and keeping the remainder as slave labor. It was called Generalplan Ost, look it up if you feel like not sleeping for a few weeks.
As for Japanese intervention in the Far East, ain't happening. First, the Far East army of the USSR was at full strength for the entire war, with more (and better) tanks, more artillery, more men, and more planes than the Japanese could bring against them. A Japanese invasion would have been a bloody failure.
Pearl harbour is conducted with the co operation with German forces to destroy the pacific fleet then drop an atomic bomb on new york, if they don't surrender then on Boston then on Chicago and so on until they gave in.
Apart from the impossibility of the Nazis getting an atomic bomb, there are lots of problems here. The biggest one is the sheer power of the United States. According to Paul Kennedy's "The Rise and Fall of the Great Powers" the US had control over approximately 41% of the WORLD'S warmaking power in 1939, and this was while the US hadn't bothered to mobilize in the slightest. It gets bigger as time goes on. Germany and Japan combined have approximately 16% (most of which is Germany). Seeing an issue here?
Is this a realistic way of how Germany could have a achieved world domination (apart from Japan)?
Sorry, but no. If you want to read an excellent World War II TL however I would recommend CalBear's Anglo/American-Nazi War, which follows the Anglo/American efforts to defeat the Reich following a Soviet collapse in 1943.
