Yesterday, on Thanksgiving Day, we lost a true national treasure, Colonel (Retired) John Collins, Warlord Emeritus at age 97. There are very, very few who have had such an impact on US national security thought as Colonel Collins. Please read his books on military strategy and military geography, special operations (he is the creator of the Five SOF Truths) and small wars and others. From his service in World War II to being General Westmoreland's planner to teaching at the National War College to his second career at the Congressional Research Service he was a prolific writer and exceptional leader, teacher, thinker, and mentor. His lasting legacy is the creation of the Warlord Loop during which for almost two decades he mentored approximately 500 national security practitioners from the military, foreign service, intelligence community, and other government agencies as well as scholars and journalists.
