No Goering no Nazis in power. I think we forget quite how popular he was at times, the man had charisma, was a hero and as nuremberg showed when he was "clean" he was a very shrewd opperator. Other parties willingness to do business with the NSDAP had a lot to do with a belief in a moderate wing to the party, as did funding. Goring was someone you could invite to a salon or a weekend in the country, he was "one of us" to the upper class with his love of hunting and the country. Although he became a bloated joke later on without him they would be in trouble way before gaining power. Roehm and Goebelles were not socially acceptable, the Strassers were suspicuously keen on the S bit of the NSDAP, Himmler was a cranky chicken farmer. Hitler an austrian immigrant with an interest in his niece. Without the big fella and before him Ludendorf, they'ld have just been a pack of cranks with an unaccountable popularity in Bavaria.
It's arguable thta if he had died in the first world war the second would never have hapened, well not against Germany anyway
