Ryan Evans had the pleasure to sit down with Oona Hathaway and Scott Shapiro, authors of the new book The Internationalists: How a Radical Plan to Outlaw War Remade the World. Remember that treaty you learned about in school that outlawed war after World War I - the Kellogg-Briand Pact? That's right, the one you laughed at.

Well Oona and Scott -- both of Yale Law School -- make a pretty strong argument that it actually worked far better than we all thought. And, in doing so, they make a good case that international relations scholars should take the power of the law more seriously.
