Has anyone ever done this? I'm not even sure if it's possible. Everything in the world has to either be owned, puppeted, or in your faction as the UK.
Some pitfalls immediately come to mind, like countries with neutral foreign policies that never cause world tension. The only way getting them to join allies is getting the AI to attack them, and that's not even guaranteed. Good luck getting the AI to declare war on Chile or Switzerland. Then there's other nations that are non-aligned, not sure if they'd join if you turn them democratic.
Then there's the Chinese United Front, if Japan doesn't dissolve that you're pretty much SOL too, cause they don't cause WT or ever leave.
You could pull some shenanigans by briefly turning fascist/communist and justifying, then turn back, but that's a bit cheating IMO and not in true flavor of the achievement.
So I guess it's impossible as of now?
