Pressfield is an old school imperialist. He argues for an American viceroy that should be set-up in Afghanistan. He thinks we can out wait the tribes with our own mercenary tribe. The conclusion by the author is that any goal should be very modest but the effort should span decades if necessary. I don't get it.
My suggestion is to let evolution do its own dirty work and get out of dodge. No effort, no matter how noble will accomplish anything more lasting than provide more monuments for Memorial Day. There is no achievable mission worth the cost of trying to fix Afghanistan.
