Who agrees that there should be a United Earth Government? All existing nation-states would already exist, but they would be federalized into less-powerful states (similar to US states). It wouldn't be some stupid New World Order conspiracy theory or anything like that, since that is just a hoax, but this would be a real legitimate peaceful and democratic world government. I think it would be a good thing. Of course, the US would probably still be the leader of the world. This new world government would of course be capitalist and democratic and have human rights and a constitution similar to the United States constitution. It would further development worldwide. It would sort of be like the United Earth in Star Trek I suppose, what do you think, would you like there to be a world government?
