If you go against Russia/China/North Korea/Iran/India, they send a hitman to assassinate you. If you go against US and its allies, they assassinate your character first and you die in an accident in the prison with the camera footage missing.
And this is if you are actually somewhat popular, if not there are a tons of black sites they where they do Russia/China/North Korea/India shit and their populace will deflect how they are more humane like their life depends on it.
