Silliman also played a prominent role with the United Nations and other Western donors to provide humanitarian assistance to Iraqis displaced by war and assure demining and stabilization efforts so that displaced Iraqis could return to their homes. After ISIL was pushed out of Iraq, he played a crucial role in implementing the policy the administration of President Donald J. Trump of focusing assistance on the
Yazidi and Christian communities that had been targeted by ISIL, aiming to limit Iranian activities in the region, defeat ISIL in Syria, and help U.S. companies conduct business in Iraq. He received the Presidential Distinguished Service Award from President Trump in 2018 for his service in Iraq.

Quds Force leader
Qassim Suleimani and Iraqi militia leader

Baghdad International Airport, Silliman was a frequent commentator on domestic and international media where he argued for de-escalation of tensions between the United States and Iran and a clearer articulation of U.S. foreign policy goals in the region. Silliman married Catherine Raia Silliman in 1990, and they have two adult children. He currently resides in the Washington, D.C. metro area. ==References==
