@hamilton,
You still haven't established that conflict of the intensity of war is inevitable in such a situation. Neither have you established that such conflicting views are inevitable. Finally, your remarks are predicated upon some imagined "one world" government, which is a complete departure from the original proposition, and really, a non sequitur to the question of whether or not democracy is "the real way to go."
It seems to me that you're attempting to cobble together an argument to the effect that democracy is 'not the real way to go." That's why i asked you what type of government you would prefer to democracy--a question you haven't answered.
