No way. I don't understand this obsession with moving toward a world government. I'm all for cooperation between countries, and frankly the US needs to show more respect to our Latin American neighbors than we do, but concentrating the government's power further from the people will only make it less responsive to their needs.
This is where I'm coming from as well. As a supporter of democracy, it is evident to me that moving governmental power
away from the people will only serve to silence their voices. If such an organization consisted of economic cooperation and nothing more, then I could accept it. When it starts adopting the trappings of a nation itself, then it must be aggressively opposed.
