Scott Horton of antiwar.com and the Libertarian Institute has a new book chronicling 20 years of America's "War on Terror." Enough Already is a compelling history of modern US interventionism and a scathing critique of American foreign policy in the Middle East. Horton joins Jeff Deist for a sobering look at American hubris overseas, along with the blowback and destruction it causes. You don't want to miss this conversation.
