Terrorism means nothing more than violence committed by Muslims whom the West dislikes has been proven repeatedly. When an airplane was flown into an IRS building in Austin, Texas, it was immediately proclaimed to be Terrorism, until it was revealed that the attacker was a white, non-Muslim, American anti-tax advocate with a series of domestic political grievances. The U.S. and its allies can, by definition, never commit Terrorism even when it is beyond question that the purpose of their violence is to terrorize civilian populations into submission. Conversely, Muslims who attack purely military targets -- even if the target is an invading army in their own countries -- are, by definition, Terrorists.
There was ample reason for concern that terrorists might be responsible.
