Regarding the cartoon that shook the world and your cowardly and spineless decision not to publish the cartoon(s), you are proving what remarkable cowards academics can be. Shame on you!

When Yale University Press publishes “The Cartoons that Shook the World” by Brandeis University political scientist Jytte Klausen in November, the book will be missing a key element: the cartoons that shook the world.
