democratic congresswoman and president of the woodrow wilson international center sfr scholars jayne harmon. the kill iing of jihady john, t victory in sinjar, those are significant developments, but i don t think we have to go overboard and say it s turning the tide. i agree, it s too early to put the banner that says mission accomplished on top of the aircraft carrier. and in sinjar they have to hold it. they with respearen t the domin fighters. it was the peshmerga that won the battle with our air cover. i don t know where this goes. we still have to get raqqa, ramadi and continue the raids. there s a lot of other stuff going on. sinjar is important because it s on that road from raqqa, the so-called capital of the islamic state. which they still control the second largest city in iraq.
