Speaking on CNN International about the United States’ new strategy to strike Islamic State targets in Iraq and Syria, Carnegie’s Marwan Muasher said that while countries like Jordan will not participate militarily, it will provide much needed logistical and intelligence support and connections with the Sunni tribes of Iraq.

The more important thing to consider, Muasher explained, is that the Islamic State cannot be defeated militarily without looking into the underlying sources that produce its fighters. That’s a challenge that countries in the region have to take on, he argued. Much needs to be done with the Sunni tribes to lure them away from giving the Islamic State a haven inside Iraq, he concluded, but that’s also going to depend on a truly inclusive Iraqi government.
