we are? I thought we were the more objective ones 
well, I think we are just as objective (and as biased) as the last few generations, but our thinking is influenced in a slightly different way than theirs is; they go by nationalism, while we go by common ethics. (in the generality, of course)
I actually kinda agree with CP on this one.
someone mark down the date and time; this is quite a momentous occasion.

The problem is, with the current situation of the world's politics and economy, it would never work. The new government would be fighting bloody guerrilla wars everywhere, and terrorism would be even more widespread than it is today.
That's true, which is why I think it must gradually come about to work correctly so that the cultural systems have time to adjust themselves accordingly. There will still be force involved, but it will go on over long periods.
What I'm saying is that a world government is good as long as not 1 country from the current world would have control. I know it will get messy when other countries also involve itself in this government but its the only fair way for countries with different policies, beliefs etc to actually thrive within this government and not rebel.
What's probably going to happen though is that the powerful countries of today will have more of a say in the new government; this is quite inevitable as long as there is an imbalance of power in today's world. (i.e. all countries are not economically, etc. equal) The others can and will get involved, but they won't have control over as much as the big nations would. (and if they rebel you can always apply force

)
Although I'm not sure that the policies/beliefs/etc. throughout the world will be all that different by the time this type of thing becomes practical, since as I said before, everyone tries to imitate the more prosperous nations even today. (in this case, the US)
