    Armies Have a Role to Play in Nation Building

    Oct 24, 2017

    Events in Iraq and Mali have raised questions about the value of Security Force Assistance and U.S. capacity to strengthen client states' militaries in the face of insurgencies or other threats. History shows that SFA programs could be improved if they focused more on ideology and how an army complements a host country's larger nation-building efforts.

    Dec 5, 2017

    Islamic State 2.0

    Many of Iraq's Sunnis are frustrated with the slow pace of reconstruction and a Baghdad government they consider too friendly to Iran. The U.S. needs to shift from supporting military operations in cities such as Mosul to helping the Iraqi government better address political grievances. Failure risks sowing the seeds of ISIS's resurgence.

    Contain, Deter, Transform: A Winning Strategy on North Korea

    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.

    As the threat from North Korea has been developing over the last 30 years, the U.S. has responsibly deployed missile defenses in Korea to protect its forces and South Koreans. Today, North Korea's medium- and intermediate-range missiles require a defense able to handle higher missile re-entry speeds like the THAAD system.

    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.
