The biggest challenge facing the United States in taking on the Islamic State will be going beyond degrading and attacking its military capabilities, said Carnegie’s Frederic Wehrey on Bloomberg TV. It will include the long term challenge of setting the political conditions on the ground to ensure that this movement doesn’t grow back, he argued.

While U.S. President Obama has stressed the importance of local governments to lead this effort, Wehrey contended that Arab participation will be symbolic in purpose. In terms of real combat capabilities, he said, the United States is going to carry most of the burden.
