20 years and $6 Trillion later...what have we gained from the Global War on Terror

Erik Edstrom is the author of "Un-American: A Soldier's Reckoning of our Longest War". In this brave and countercultural book, he dissects why our Department of Defense has become so wasteful and ineffective. We have not won a war decisively since WWII but our expenditures on defense have skyrocketed beyond the GDPs of 70% of the world's countries. What is behind this rise? What is the opportunity cost (where could those dollars be spent for greater return)? Erik and I have a thoughtful conversation about our times in Afghanistan and what is next for military service.
