You're quite the optimist. I'm not. I can think of other outcomes: Wasn't Hitler elected by a democracy?
"Wasn't Hitler elected by a democracy?"
As a matter of fact, no. The election of Hitler is one of those "facts" that EVERYBODY knows, but just isn't so.
The Germans that election elected national hero Paul Von Hindenberg. The nazi party only garnered about a third of the vote, but the field marshall thought it good politics to placate this minority by APPOINTING Hitler to the post of Chancellor.
If Hindenberg had been less a soldier and more a politician this might have been a good idea too.
I can think of other outcomes
There are (and never were) any guarantees in this thing. The alteratives to spreading freedom to this part of the world are...what? Turning (say) Syria into a glowing hole in the ground? Slaughter 30-40 million people?
