Why Did So Many Muslims Seem to Celebrate 9/11?
The seeds of hatred

From the moment Americans learned that the 19 aerial assassins of September 11 were Muslim Arabs, they began to wonder: What did Islam have to do with it? The answers were plentiful and quick to come but often contradictory and confusing. Heads of Muslim nations and leaders of Islamic organizations emphasized that Islam was incompatible with terrorism and intolerance. And the spirit of the oft-quoted line from the Koran, "Let there be no compulsion in religion," seemed to reassure most of America's religious, civic, and political leaders. "The face of terror," President Bush confidently announced, "is not the true faith of Islam."
But if all that were true, why did so many inhabitants of the long Muslim "street," stretching from Morocco to Indonesia, appear to be overjoyed by what Osama bin Laden's henchmen had accomplished? For that matter, why were certain Islamic jurists in Pakistan issuing
fatwas directing Muslims to fight American infidels if they attacked Afghanistan? And why do firebrand clerics throughout the Islamic world continue to issue equally inflammatory decrees? Most disturbing, some of those same voices of moderation had occasionally expressed their approval of Islamic groups such as Hamas and Hezbollah that engage in terrorism.
