The two Uzbeks and one Kazakh who were arrested this week in Brooklyn for allegedly making plans to join Islamic State found their way to the extremist group only after they immigrated to the United States. You have to wonder whether there's something about their experience in the U.S. -- rather than the Central Asian countries they left -- that inspired them to radicalize. Were these two mobile phone repairmen and gyro seller inspired by a sense of betrayal or disgust at the American way of life?
