The more diverse the more decentralized and lightweight, or the more tyrannical, a government must become in order to prevent states from breaking off ... I don't personally believe that anyone could hold the entire world by force, and I'm fairly certain that a government that everyone was willing to be a part of would be so powerless that it would be meaningless to join.

In my opinion arguably the UN is already an extremely lightweight and ineffective world government.

It can either be looked at as a hopeless world government or a somewhat effective international body.


Personally I can see the UN gaining more influence over its members as he world becomes more globalised essentially meaning that sovereignty will be slightly broken down as human rights abuses and the suchlike will not be tolerated. Either that or the UN could lose some of the mild power it does have and essentially become a discussion forum for the world.

that's how i feel. If there was another enemy outside the earth, the earth would be forced to be cast their differences aside and unite.

Exactly as Kantor hath spoken. Right now Earth is all there is, there is no way all there is will ever unite. As soon as there is something else, aliens or, say, other colonized planets that begin to be autonomous, we will band together.

No. It's possible that the countries of earth will one day unite in the pursuit of space travel (which would be awesome), but we would still be separate nations.

Once the Apocolapyse happens and Jesus comes down to the earth.

Its already happening.

Yes, under Satan, which will unite mankind under the beast(their inner primitive nature) and we'll all come to accept what we are, and the world will live happily ever after.

Never happen. We're all too greeedy for any kind of world unification to that extent.
