Dr. Jarret Brachman's The War Within: A Look Inside al-Qaeda's Undoing delves into al-Qaeda's crumbling global movement and its internal struggles, including its attempts to remain relevant. While at one time not a day would go by without al-Qaeda being mentioned in the news, media coverage is now much more focused on the Islamic State of Iraq and Syria (ISIS), which has dominated al-Qaeda in terms of strategic messaging, recruiting, funding, and more.
