"Whosoever, therefore, out of a state of Nature unite into a community, must be understood to give up all the power necessary to the ends for which they unite into society to the majority of the community, unless they expressly agreed in any number greater than the majority. And this is done by barely agreeing to unite into one political society, which is all the compact that is, or needs be, between the individuals that enter into or make up a commonwealth. And thus, that which begins and actually constitutes any political society is nothing but the consent of any number of freemen capable of majority, to unite and incorporate into such a society. And this is that, and that only, which did or could give beginning to any lawful government in the world." -- John Locke
The Locke quote logically validates mob rule also.
All of the quotes you've presented here have been cut to limit their extent to logically justify any rule including the present govm't in Iraq. The people there do will it to continue you know, there is effective opposition. That's amazing, since it does lie in the lands of Allah and the world of jihad. If the people don't will it, how come the jihadists aren't active there? Is the govm't of Iraq a just form of govm't, or is it simply justified , because it was established and controlled by an effective majority of freemen?
