World War I was called "the war to end all wars," but nearly 100 years later, war is far from over.  Adam Hochschild, co-founder of Mother Jones magazine, has written a new book looking back at that war and specifically, those who objected to and fought against the Great War.

Adam joins Laura in studio to discuss World War I, the anti-war movement then and now, and why we're still struggling to articulate an opposition to war that will successfully end all wars.
