The Japanese had NO history of democratic processes and a religion based on the diety of the emperor. No, their present form of government is NOT exactly like ours, but it's their form and look at how long THAT took to get up and running.
Nobody, well, I'm not, saying that what finally emerges in Iraq will be a government that is a carbon copy of what we have in America. Why don't you climb down from that pedestal and look at what is actually posted to you, instead of seeing what you imagine you see?
Cyprus has had a very long history, predating Ataturk, of waring factions of Greeks and Turks. The Greeks don't have clean hands either and Greece has been a Commie/Socialist nation since WW II.
