I doubt in the existence of a single world government but i believe in the concept of countries forming alliances with the aim of total Global domination, The US and its Allies in NATO are for the same thing, The Chinese were late to the party and are currently trying to build up allies mainly in Africa and also in Asia, they are making inroads in South America as well. Russia with the dissolution of the Soviet Union have to start from scratch because most members of the Soviet Union despises them. They seek allies with ruthless aggression just like the Nazi's did.
