A lot of what you need to know about Islamist terror was revealed today as suicide bombers killed scores in Shiite shrines. They do not represent Islam; they do not represent Iraqis; they represent nihilist murder and aspirations to totalitarianism. Maybe these explosions will help Iraqis realize that our enemies are their enemies. It is certainly hard not to be sickened by the sacrilegious nature of their atrocities.
