re: What would the world be like if the NAZIs had won?

It would not end as far as German occupation and taking over countries. The end goal was one rule and that of Germany. Israel was already underway as my understanding is, in that those folks were migrating to the 'homeland' at the time. With the motivation Hitler had for annihilating the Jews, I doubt he would let it stand.
It would be interesting how historically it played out in that one force, the Germans, were to bring about the end of times, by more or less, forging the path to the Second Coming.
Economically, Germany would have taken all the oil that Africa, the Middle East, Russia, the United States, South America and whatever else they wanted if they had won the war. The world would be run by Germany as they would be in control of those resources. They could control price, production and supply.
The Germans were the first to military technology from the bombs to rockets. The story would have been much different and I believe this technology would have been used much more severally on the world than what has actually transpired in history.
