This week’s episode from GritTV focuses on modern warfare and US imperialism. Is drone warfare here to stay? It’s one of the few things Republicans and Democrats agree on. Andrew Cockburn has been a rare critical voice on the subject. He is the Washington editor of Harper’s magazine and the author of several nonfiction books on war and international politics. His new book is Kill Chain: The Rise of High-Tech Assassins. And later in the show, an excerpt from a new film about a young man held in the US prison at Guantanamo, Fahd Ghazy.
