Does Obama need a new strategy to fight ISIL?

In the last two weeks, fighters for Islamic State in Iraq and the Levant (ISIL) have captured the Iraqi city of Ramadi and the ancient Syrian city of Palmyra — resulting in major victories for the armed group, also known as ISIS, and painful blows to the U.S.-led coalition trying to destroy it.
