I've been struck over the last several days by the reactions of Shiite and Sunni Muslim devotees to the bombing of the Askariya shrine in Iraq on Wednesday. This act of senseless destruction and willful desecration, presumably perpetrated by Sunni-connected insurgents, has unleashed a spasm of tit-for-tat mosque-bombings, the murders of at least three imams, and the kidnapping of yet another cleric.
