The Hitler thing could theoretically work, provided you time it right and get some additional people.

An assassination during the Beer Hall Putsch would be perfect. He was already wounded, and just a bit more would mean no country club prison, and no mien kampf.

Further, no show trial to make Hitler even more popular.

Hitler would be mocked for trying to overthrow the government in the most stupid way possible, and then getting gunned down for it.

Now, Germany would still be ripe for an authoritarian take over, but that's where the second assassination comes it. A man named Carl Schmitt.

This fucker lived until 1985, and that's far too long for a Nazi. He laid down the philosophical justification for Nazism, both before Hitler's rise to power and during.

He fell out of favor and was expelled from the party, but that was it. No reprisals.

Schmitt is also Peter Thiel's favorite philosopher.

So tag Schmitt in 1916 when he volunteered for the German army. This is before he wrote his first love letter to dictatorship and his blueprint on how to dismantle a liberal democracy through fear mongering and scapegoating.
