One world government?

[Aoi Magi]

One world government won't work because there would be no one to challenge that authority. I on the other hand do agree that we need to lower the current count of governments. Maybe 3 strong governments would be the best bet. Too many powers and we get all the conflicts as we see today, too few and a dictator is bound to rise up and ruin everything, so a balance is necessary.

Considering most significant challenges to authorities of influential nation states do not come from abroad, the same influences which can challenge authority of powerful nation states today can challenge the authority of a world government just as well.

Actually governments do worry about other governments, and it is one of the primary reasons why we don't see as many wars. If a single superpower establishes itself without any opposition, people and states won't stand much of a chance against it. When we think of a government we imagine a democratic system where actual power is still somewhat with the people, but with a one world government that wouldn't be the case, it would be like being under a single king who if good, might make the system work, but if bad, then it would devastate the entire world.
