Abstract: One spring more than twenty years ago, David Kennedy visited Ana in an Uruguayan prison as part of the first wave of humanitarian activists to take the fight for human rights to the very sites where atrocities were committed. Kennedy was eager to learn what human rights workers could do, idealistic about changing the world and helping people like Ana. But he also had doubts. What could activists really change? Was there something unseemly about humanitarians from wealthy countries flitting into dictatorships, presenting themselves as white knights, and taking in the tourist sites before flying home? Kennedy wrote up a memoir of his hopes and doubts on that trip to Uruguay and combines it here with reflections on what has happened to the world of international humanitarianism since.
