It is extremely inconsistant from book to book. Stark's position in Civil War was the only sane one, which some writers like JMS chose to portray as naziesque for some weird reason.The CW would not be have been half as bad idf Tony had at least tried to act withing the bounds of morality and Law while enforcing an evil law that is hard but not impossible.
Whatever... It wasn't Stark that oppointed Osborn king of the world.Dark Reign comes directly from Tony fighting with the government to be able to use Super-villians to hunt Heroes. Without that action from him and Reed there would have been no Dark Riegn
