A conservative explanation why the ISF collapsed - before Mosul - which is a good, quick read:http://www.theamericanconservative.c...d-army-failed/

It ends with:
One thing is clear: the foreign armies that the U.S. invests so much money, time, and effort in training and equipping don’t act as if America’s enemies are their enemies. Contrary to the behavior predicted by Donald Rumsfeld, when the U.S. removes those “training wheels” from its client militaries, they pedal furiously (when they pedal at all) in directions wholly unexpected by, and often undesirable to, their American paymasters. And if that’s not a clear sign of the failure of U.S. foreign policy, I don’t know what is.

The more I read the more I wondered is the ANSF next.
