Thomas F. Lynch III Authors: Amira Jadoon with Andrew Mines Reviewed by Thomas F. Lynch III, PhD, Distinguished Research Fellow, Institute of National Strategic Studies, National Defense University Dr. Thomas F. Lynch III offers his expertise in a thoughtful review of this "essential primer" on the Islamic-State Khorasan Province (ISK). While finding the book's idea that the ISK is currently a "latent, global terrorist threat" to be "less persuasive," Lynch highlights the value of author Amira Jadoon's unique ability "to write with an appropriate level of depth about the complexity of tribal groups, subgroups, fragments, and splinters" and notes that "There is no other published work today with such a high level of insight into this enduring regional terrorist group."
