No, Allen, I don't think the united World I propose is the least bit unrealistic, it's just not going to happen in one day or one year, that's all. It has been gradually happening for the last few thousands of years as we have progressed slowly from wandering families, to wandering little tribes, to larger tribes, to nations, to trade alliances, to literacy, to universal education, to international laws, and so on...

Impulses toward larger and more harmonious associations of people are wise and inevitable. Impulses toward greater division and segregation of people are unwise and counterproductive.

It's that simple. But it doesn't all happen in one glorious instant solution.

The best way to unite the many diverse factions you describe in the Middle East, Allen, is to ensure that they all experience improvements in health, economic well-being, education, legal protections, and safety from violence. That can be done bit by bit. in stages. No society can fix everything overnight.

I am simply suggesting constructive efforts, as opposed to efforts that produce more conflict.
