Michael Totten: ‘What Just Happened In Syria:’
‘Look. Running guns and ammo under the radar to legitimate proxies in a fight against a terrorist army is entirely reasonable behavior on the part of the United States government. We’ve been doing that sort of thing for decades. Pretty much everyone else in the Middle East does it, too, but they almost always run guns and ammo to terrorist organizations rather than to groups fighting terrorist organizations.
Regardless, it’s high time we come out and say exactly what we’re doing and why. Everyone already knows we’re backing the Kurds against ISIS, and everyone already knows the Turks would rather see an ISIS victory than a Kurdish victory. None of this is even remotely a secret. It’s all right out in the open. Official denials aren’t fooling anybody.’
In his book Where The West Ends, Totten describes visiting Northern Iraq briefly as a tourist with a friend, and the general feeling of pro-Americanism in Kurdish Northern Iraq that generally one can only feel in Poland, parts of the former Yugoslavia etc.
