    Rolling Back the Islamic State

    Apr 20, 2017

    The Islamic State has lost substantial control of territory and people. But the group still conducts and inspires attacks around the world. The United States should pursue a light rollback strategy that relies on local forces backed by U.S. special operations troops, intelligence assets, and airpower.

    The U.S. Strategy to Defeat the Islamic State Needs an Overhaul

    May 8, 2017

    A broader strategy to beat the Islamic State should address the conditions that allowed the group to emerge and thrive. A long-term commitment is required to establish legitimate governance in Iraq and Syria and reconcile the disenfranchised Sunni Arab populations with their governments.

    When the Car Is a Terror Weapon, Can We Prepare for Attacks?

    Soft targets, so-called because they are more vulnerable to terrorism due to lower levels of security, are notoriously difficult to protect, and the latest shift to using vehicles to conduct ramming attacks only compounds the problem for authorities.

    Will al Qaeda Make a Comeback?

    Al Qaeda's revival will likely hinge on its ability to take advantage of opportunities such as the withdrawal of counterterrorism forces from key battlefields, more revolt in the Middle East, U.S. or European policies that feed the perception of Muslim oppression, or the rise of a charismatic jihadist leader.

    If and when self-declared Caliph Abu Bakr al-Baghdadi is killed, it will have little effect on the threat posed by the Islamic State to global security. The far more important objective is to continue dismantling the organization as a whole, including its affiliates in Libya, Egypt, Nigeria, and Afghanistan.
