In October 2017, reporter Ronan Farrow in The New Yorker, and Megan Twohey and Jodi Kantor in The New York Times, broke the story of Harvey Weinstein's long history of sexual harassment and predatory, retaliatory behavior.
At the same time he was investigating Weinstein, Farrow had another huge project in the works: a sweeping exploration of the decline of American diplomacy.
Farrow spoke at Harvard's Memorial Church in front of a live audience on May 2.
