Berger of the Brookings Institution, Daveed Gartenstein-Ross of the Foundation for Defense of Democracies, Dr. Michael Knights of the Washington Institute for Near East Policy, Aron Lund of Syria in Crisis, Alex Mello of Horizon Client Access, Douglas Ollivant of the New America Foundation, Aymenn Jawad al-Tamimi of the Middle East Forum, Craig Whiteside of the Naval War College, and Aaron Zelin of the Washington Institute for Near East Policy.
