ISIS terrorist group potential threat to US, Crenshaw says

Martha Crenshaw, a senior fellow at CISAC and FSI and one of Stanford's leading experts on terrorism, says the terrorist group known as ISIS poses a danger to the United States if it grows more powerful. But that organization, she adds, may be overreaching in its ruthlessness and religious zealotry. Crenshaw answers questions in this Stanford Report interview with the Stanford News Service.

Meanwhile, the U.S. government has not found a way to deal with the larger Iraq conflict that now involves ISIS, says Crenshaw, who founded and runs the Mapping Militant Organizations project.
