I don't remember anyone claiming that Romania was the best place in the world, just that we were aiming toward marvellous things.
The propaganda in the U.S. is that everyone is middle class, that the rich deserve to be rich, and that the U.S. is the best place in the world to live.
Perhaps it makes no sense to discuss the truth value of propaganda, but I don't really see a huge diff between the examples given.
