An organization capable of steamrolling over nations need not be another nation. I could see huge international companies the like of Google having the might to fight nation states.
True that. If nations have no sense of national culture and identity, then corporations inevitably become more powerful because they are still able to operate in a coordinated fashion, by "virtue" of being directed by a single person.
Actually, I suppose a lack of national culture or sense of national identity would also weaken democracies more than dictatorships.
