The Daily Beast has described him as one of “the most trusted authorities on the al Qaeda network because of his encyclopedic knowledge of terrorist biographies.” In 2007, he published a monograph titled, Iran’s Proxy War Against America, which details Iran’s decades-long sponsorship of America’s terrorist enemies. In 2008, he completed an exhaustive review of the Guantanamo Bay detainee population, cataloging and analyzing thousands of pages of declassified documents.
