The Internationalists by Oona Hathaway and Scott Shapiro

The Internationalists by the legal scholars Oona Hathaway and Scott Shapiro, explain a phenomenon you probably didn’t even know existed — the decline of interstate war and conquest — with a historical event you probably think is ridiculous: the Kellogg-Briand Paris Peace Pact of 1928, which declared war illegal.

"But in their gripping and evidence-rich book, they make a plausible case. And like The Clash of Civilizations and The End of History, the book presents a sweeping vision of the international scene, making sense of many developments in the news and recent history."

- Steven Pinker, Johnstone Professor of Psychology, Harvard University, and the author of ten books, including the forthcoming Enlightenment Now: The Case for Reason, Science, Humanism, and Progress
