I disagree with the world In in Chaos part and they would have fallen from power...I will now play the role of Nazi Defense Lawyer
Whenever a Powerful empire falls from its place in the world people go back and point out how bad they were. From what we know the Nazi's were pretty far advanced with some of thier plans becoming new weapons we use today ( B-2 is a good example and so is our Ballistic Missiles and A-10 I believe) They were far advanced with thier military, If it hadn't been for Hitlers ego they would have had a Nuclear weapon before us but he decided he would win europe without it. If Hitler had won, Then Most Liky He would have not stopped at Russia. he would have most likly went down through Turkey and started fighting the former british empire in The Middle east ( This is due to the fact if Hitler won Britian would be the largest slave island). Hitler then would have probably come up and went through the center of Russia agian. ( if it wasn't for America thier is no denying Russia would have most likly fallen). and Knowing Hitlers ego he would have ran right through china and attacked His allie's in japan. . This is on the Eastern Front. In Africa he probably would have pushed down, not with tanks and men but with Bombers and he would attack the the peopel directly. Then send in an occupation force (remeber back then Modern African Weapons were basicly a stick,stone and a knife). After Hitler had taken and took what he wanted from Africa he most likly would have finished Switzerland off, And Most Likly in the late 50's or early 60s right now Hitler would finaly take on America. From Both the Atalantic and Pacific Front's Basicly Boxing America in ( we know as of now the germans had plans to build a long range bomber and bomb NYC, als Nazi Personnal were actualy in NYC planning on an attack during WW2.) Since America at that time would have never got thier military truly built up because they would have not truly enetered the Europe war they would have thier butts kicked and we would be singing the Praises to Hitlers Daughter...( Another Historian Thingy people believed Hitler had a daughter because of pictures found.) Remember also Hitler just now turned 115 like last year so he would have ruled into at least the early 80's.....
Okay I am now off of the Nazi's Defense....
