In Spain on March 11, 2004, “a group of mostly Moroccan Spaniards had launched multiple bombings on Madrid’s transportation system, killing 191 and wounding hundreds more, attacks designed to protest Spanish support for the war in Iraq. …the Madrid attacks were largely the work of leaderless jihadis who financed the bombings with the proceeds of substantial drug deals, and only some of whom were affiliated with a known jihadist organization, the Moroccan Islamic Combatant Group. The Madrid attacks worked; a new Spanish government quickly announced that it would be pulling its troops out of Iraq.”
