he only time the Americans got involved was when the oil fields were threatened

"The American policy is shameful," said Hassan al-Fayath, the dean of al-Nahrain University in Baghdad. "The Americans always say they are the leaders in fighting terrorism but they didn't lift a finger when Isis was taking parts of Iraq. The only time the Americans got involved was when they found it started threatening their interests by getting closer to the oil fields and to Irbil." (thanks Amir)
