Speaking of WW3, considering the nature of Nazi succession conflicts, I wouldn't be surprised if the next succession sees WW3 be caused by it.
Nazis really are not really worried about consueqences unlike Soviets. They just could begin that. It had always been really close but fortunately führers who have planned that died before that. But how long such luck can last?
WW3 would be really shitty thing when it would mean complete devastation of Europe, North America and Middle East. Probably good part of Africa would be too devastated.
