Used their knowledge to develop new weapons during the war instead of wasting resources and time exterminating them... but you would say this would not make them nazis even when they still hate jews but would want to use them instead of exterminating them.
But if Hitler still hated the jews but used them for the war then we would have a different story if we are talking about the development of the atom bomb?
I know it was a joke and that was actually impossible to think that would be successful but the Nazi party had larger numbers and could of taken part in a coup.
If Germany developed the atom bomb in 1942 then they could force America in peace. But that would be 'impossible' by some people on here although that is alternate history.
Since you are so pessimistic about Germany being able to win the war then I ask you this.
In any situation ever possible could Germany ever win the war? People/personalities/events/weather could all change.
