For weeks the Iraqi's have been fighting Isis with US air support.  What was needed was more boots on the ground which the US wouldn't send;  we then asked our friends and allies for help.  All we heard was the sound of crickets.  Now it seems the needed help has come from the Iranian army.  With their help the Iraqi's are pushing Isis out of Iraq and winning.  Regardless that the Iranians are against Isis for religious reasons.  The enemy of my enemy is my friend.
