I hate to sound CLintonesque, but my answer is, it depends how you define “ever.”
If you mean “in a few centuries,” the answer may be yes. If it means “in out lifetimes,” there’s almost no chance.
Abut fifty years ago, a prominent British diplomat was asked when world government would be feasible, and his facetious answer was “shortly after the formation of the state of Israbia.” His point was, if Arbas and Jews can’t coexist peaceably in one small strip of land, what are the odds that hundreds of races/religions/ethnic groups can agree on what a government should be like?
Thnk about it- right now, Canada is a beautiful, peaceful, prosperous, democratic country. Its people have EVERY reason to be happy, and yet it’s constantly on the verge of collapse because its French-speaking citizens want out. If multi-ethnic government can’t last in a country like Canada, it’s hard to imagine where it could.
Will institutions like the E.E.C. bring about world government? In a limited sense, perhaps. But even as countries officially place themselves under the E.E.C.'s control, ethnic tension is eating away at them from within. The Flemings and the Walloons still don’t get along, and continually talk about breaking up Belgium- BELGIUM, for crying out loud. Again, if a government in a country as free and prosperous as Belgium can’t keep two ethnic groups happy, how can one government keep all the nations of the world happy?
The USSR collapsed. Yugoslavia collapsed. Indonesia is shaky. Multi-ethnic and multi-religious African countries are constantly wracked by civil wars. Think Rwanda’s Hutus and the Tutsis will agree on one government in the near future?
Nationalism SEEMS like such a quaint, antiquated, obsolete notion, and so intellectuals tend to dismiss it, or to assume it will fade away. Don’t bet on it. Like it or not, nationalism is powerful, and it’s a GROWING force, not a dwindling force.
I’m not one of the right-wing wackoes who thinks the idea of "world government"is evil or part of a sinister plan by the Trilateral COmmission or the Banks or the Jews or the (fill in your favorite paranoid fantasy). I just don’t see any way it could be feasible for a LOOOOONG time. So, don’t expect that you’ll live to see the “Star Trek” fanatsy of all races living together in harmony under one benevolent government.
