Durden concludes the article with this perceptive statement:
So it appears that the US allowed ISIS terrorists to freely leave areas under coalition control, according to no less than the BBC, while at the same time attempting to make the case before the public that a permanent Pentagon presence is needed in case of ISIS' return. But it’s a familiar pattern by now: yesterday's proxies become today's terrorists, which return to being proxies again, all as part of justifying permanent US military presence on another nation's sovereign territory.
America's Syrian adventure went from public declarations of “we’re staying out” to “just some logistical aid to rebels” to “okay, some mere light arms to fight the evil dictator” to “well, a few anti-tank missiles wouldn’t hurt” to “we gotta bomb the new super-bad terror group that emerged!” to “ah but no boots on the ground!” to “alright kinetic strikes as a deterrent” to “but special forces aren’t really boots on the ground per se, right?” to yesterday's Mattis declaration of an open-ended commitment. And on and on it goes.
