Governments are the equilibrium that comes from the reality that people will do anything, including violence, to get what they want and everyone will always have unmet desires. Wars are a disturbance in that equilibrium. I think what will eventually make governments behave better is a free market in governments and ease of movement. You basically want the entire world to be so interdependent on each other that the incentive for war is far worse than the incentive for business. It would be horrible for China to attack the USA at this point for example. You point out yourself that the US government is a vote collecting machine, which is how the incentive system was created in the first place. The entire money system is a social contact that organizes human behavior for example. Creating social contacts that people will follow to organize humanity is very difficult.
