Most Iraqis disagree, although I will admit that from an American perspective we need some sort of murderous dictator in there.
unfortunately, you cant win for losin.
if the us props up another tin pot tyrant, we are "supporting evil" much like they claim when the US supported assad in syria, the lesser of a great many evils, mobarak in egypt, the devil you know, or the palahvi regime in iran, an asshole sure, but an asshole who was turning that country from shithole to toilet, slowly but surely.
if we support the populist upstart, we are supporting the dickhead who will certainly turn on us soon.
if we do nothing, we are "enabling" the populist demagogue, the tin pot dictator, or the anarchy that comes when one or the other butchers his opposition.
if the west goes "Hands Off" in asia minor and north africa, then their lassiez faire solution will be a bloodbath, oil exports will dry up, the people will starve, and a new tin pot dictator will rise up and start doing shenanigans.
there is no solution as long as the left demands perfect solutions or total disengagement, and screams bloody murder if imperfect solutions are implemented, or the region is left to wallow in it's own crapulence
