Ten years ago today the world witnessed the single largest mobilization for peace in history. In the run-up to the war in Iraq, an unprecedented number of people — estimates range from eight to 30 million — rallied worldwide on Feb. 15, 2003 to demand the U.S. give peace a chance. On every continent people surged into the streets — from Kiev to Mexico City, from Helsinki to Cape Town, from Melbourne to Tel Aviv. A demonstration was even held in Antarctica, where a group of scientists rallied for peace at icy McMurdo Station. In the wake of this unparalleled global action, The New York Times dubbed the peace movement “the second superpower.”
