The Center for Immigration Studies hosted a panel on one of the most politicized, taboo, and chronically misunderstood threats to the U.S. Southwest Border: the national security risk posed by long-haul illegal border entry of migrants from nations of terrorism concern in the Middle East, South Asia, and North Africa. 
The starting point for conversation is a new book, America’s Covert Border War, The Untold Story of the Nation’s Battle to Prevent Jihadist Infiltration, by Todd Bensman, Senior National Security Fellow at the Center for Immigration Studies.
