In three decades under the leadership of Kenneth Roth, Human Rights Watch grew to a staff of more than 500, conducting investigations in 100 countries to uncover abuses - and pressuring offending governments to stop them. Roth has grappled with the worst of humanity, taken on the biggest villains of our time, and persuaded leaders from around the globe to stand up to their repressive counterparts.

The son of a Jew who fled Nazi Germany just before the war began, Roth grew up knowing full well how inhumane governments could be. He has travelled the world to meet cruelty and injustice on its home turf: he arrived in Rwanda shortly after the genocide; scrutinized the impact of Saddam's invasion of Kuwait; investigated and condemned Israel's mistreatment of Palestinians. He directed efforts to curtail the Chinese government's persecution of Uyghur Muslims, to bring Myanmar's officials to justice after the ethnic cleansing of Rohingya Muslims, to halt Russian war crimes in Ukraine, even to reign in the U.S. government. Roth's many innovations and strategies included the deployment of a concept as old as mankind - the powerful tool of 'shaming' - and here he illustrates its surprising effectiveness against evildoers.

This is a story of wins, losses, and ongoing battles in the ceaseless fight to rend the moral arc from the hands of injustice and bend it toward good.
