Interesting discussion.
If Hitler was dead, though, we might not have had the Battle of the Bulge. That was Hitler’s brilliant plan, iirc.
Actual military men would run the war? That could have cost more lives on both sides, by this point I think Germanys’ defeat was inevitable
We are in hypothetical land now, but I agree that even if Stauffenberg could have seized power I’m pretty sure the Big Three would have said, fine, but we want your unconditional surrender. The German Army and people were not there yet in mid-1944.
