Craig Whitlock, investigative reporter for the Washington Post, discusses his new book, Afghanistan Papers: A Secret History of the War, which is based on thousands of interviews and direct source materials from those involved at the top levels of our government and military and those at the ground level. Whitlock discusses mission creep, nation building, the distraction of the Iraq War, the disconnect between what the public was told by leaders from both parties and the military and what was actually happening on the ground, and much more.
