(Project Syndicate) – My three-year-old niece believes strongly in the power of “the good guys.” Whenever I visit, she drags me to the bookshelf in her room and pulls out book after book, each with the same conclusion: in battles big or small, the good guys always win. I don’t have the heart to tell her that, in the real world, clean fights and gratifying outcomes are the exception. Modern warfare follows no rules, and loyalties are never black and white. For me, nothing illustrates this truth more terribly than the surge in violence directed at schools and educators in conflict areas.
