Yet now the administration's critics, in part as a result, seem unaware of the significant changes taking place," said Mr. O'Hanlon, a senior fellow at the Brookings Institution, and Mr. Pollack, director of research at the Saban Center for Middle East Policy at the same liberal-leaning think tank.
