In April 2014, ESPN published a photograph of an unlikely duo: Samantha Power, U.S. ambassador to the United Nations, and former national security adviser and secretary of state Henry Kissinger at the Yankees-Red Sox season opener. In fleece jackets on a crisp spring day, they were visibly enjoying each other’s company, looking for all the world like a twenty-first-century geopolitical version of Katherine Hepburn and Spencer Tracy. The subtext of their banter, however, wasn’t about sex, but death.
As a journalist, Power had made her name as a defender of human rights, winning a Pulitzer Prize for her book A Problem from Hell: America and the Age of Genocide. Having served on the National Security Council before moving on to the U.N., she was considered an influential “liberal hawk” of the Obama era. She was also a leading light among a set of policymakers and intellectuals who believe that American diplomacy should be driven not just by national security and economic concerns but by humanitarian ideals, especially the advancement of democracy and the defense of human rights.
