Goering: Knocks Himmler about the head, tries to take power. Fails. Civil war.How different would the Hot War have been if Hitler remained in good health and didn’t have a stroke allowing Himmler to take charge in 1958?
How about if Goebbels or Goering were in the room when he had the stroke instead of Himmler?
Goebbels: Reluctantly backs Himmler for multiple bungs (pretty much as is).
Hitler lives probably no bio/chemical attacks (his fear of them was about his only restraint and even then only on the battlefield). Probably a slower advance but Germany maybe doesn't get nuked and anthraxed (although tactical and strategic nuke strikes are likely inevitable sooner or later). War might last an extra year but with less casualties over all. Assuming the illness lets him he probably does himself as the allies close in, if not he gets a bodyguard to give the coup, no way he lets himself get taken alive.
Beyond that I'm sure Calbear would have some amazing ideas.
