War Is a Lie is a thorough refutation of every major argument used to justify wars, drawing on evidence from numerous past wars, with a focus on those that have been most widely defended as just and good. This is a handbook of sorts, an engaging, always informative manual that can be used to debunk future lies before the wars they're deployed to justify have any chance to begin.

For this edition of the book, the original 2010 version has been updated and expanded with material on lessons from America's most recent wars, more pointers on what can be done to end warmaking, and an epilogue that analyzes new trends in war lying and in resistance to it. No one to whom you give this book can claim they haven't been warned!
