In order for this to work, I suppose we have to get rid of Hitler somehow. Imagine whatever you will--he was killed in WWI, emigrated to the US, was shanked in prison after his Putsch, whatever.
Who would have replaced him? Namely, I'm partial to any strong conservative leader without a Nazi bent but with ironclad links with the Wehrmacht. Basically, I'm interested in a TL without Hitler and the Nazi Party, with the military becoming the driving force in post-WWI German politics.
So, who would have "replaced" Hitler? What would a conservative, stratocratic Germany look like and how would it have acted? Would it have been better received by the Western powers?
