Blairwitch said in the "Historical Figures With Mental Issues" thread that Hitler had suffered a traumatic brain injury in the July 20 bombing.
Brain injuries can be weird things--Liam Neeson's late wife fell and hit her head, seemed fine, and was dead within a few hours. Brain bleeds, you know.
So...
WI Hitler survives the bombing per OTL, presides over the suppression of Von Stauffenberg and their ilk, and then dies that night in his sleep?
V.S. and the immediate Valkyrie plotters are doomed, but some of the ones nailed later on (like the guy in Wolf's Lair's communications bunker) might be overlooked in the factionalism following Hitler's death.
