Don't use a foreign militia with no interest in the people of the area to be re-taken

Kurds Fear the U.S. Will Again Betray Them in Syria comes from the incorrect use of the Kurdish pesh merga as an imperial force to conquer Sunni Arab regions as a means to oust ISIS and its caliphate. The Kurds have a desire to make a homeland nation for which their militia will fight with a zeal that out did Daesh's defense of Kobani, a Kurdish city in northeastern Syria. It made the U.S. military believe that their fighting ability should be used for retaking Arab cities regions.  No doubt promises were made to the Kurds about unifying their eastern region with a western Kurdish region split by an Arab region. But taking Arab regions is an overreach for the Kurds because they do not have the political will to govern Arab people. What is clear in the Middle East is that each tribe, clan or people does better governing their own and that is why both Syria and Iraq are currently balkanizing into their separate regions and any attempt to deny it is a useless waste of blood and treasure, particularly when we use a foreign militia with no interest in the people of the area to be re-taken.
