At the rate the world is going now, I have also come to a conclusion that one country should unite the world by force. Though it does not sound pretty, that is the best solution in my opinion. But the problem with this is, which country deserves to run an entire planet? Only the fittest of nations deserves to rule over all, so that we may advance. Perhaps instead of just going out and choosing a country to rule the world with the possibility to screw up humanity, perhaps we should start out slowly by having a nation that acts as earth's "spokesperson". If any extraterrestrial contact is ever made, then at least we have a representative. That way nations on earth can all collaberate without having to give up their positions of power.
