Journalist Ronan Farrow's new book, "War on Peace: The End of Diplomacy and the Decline of American Influence" looks at the longterm decline of the State Department and what he calls the growing militarization of U.S. foreign policy. Farrow spent several years working at State, including in the Office of the Special Representative for Afghanistan and Pakistan. Last week, the New Yorker won a Pulitzer Prize for Farrow's coverage of sexual assault claims against Hollywood's Harvey Weinstein. Farrow joins "CBS This Morning" to discuss America's shifting approach to diplomacy.
