P.S.
I suppose This post on the rotting of the U.N. earlier this evening set me along this line of thinking.
I always thought when I was young that a world government was a good idea, but based on the solid principles underlying a free society. Limited, and protective of individual rights.
Now, with few exceptions, almost anyone proposing "world government," with world courts and other such entities, has in mind some socialist, highly-centralized authority with massive control over almost every aspect of your existence. I ain't interested.
But maybe some loose confederation, with a simple constitution, could work.
