Time to Rethink The U.S. Drone Program?

Andrew Cockburn, @andrewmcockburn, author of “Kill Chain: The Rise Of The High-Tech Assassins” and Washington editor for Harper's Magazine, @Harpers examines the U.S. drone program since its inception. He believes the program has had few successes over the years, and that the U.S. should find a new strategy to wage the war on terror.
