The United States has, at least, complained of the participation of Iran in the terror. We know that it is relatively easy to manufacture improvised weapons to festoon along highways and byways. But the explosives being used are increasingly sophisticated and can't be attributed to volunteer young terrorists out for an afternoon's play.
The very first and most important step that needs taking is a denunciation of the tactic by Islamic leaders. Many, in the past six years, have issued routine pronouncements against terrorist bombings. But we have yet to hear the kind of denunciations one finally got from the Christian community over the genocide of Adolf Hitler.
There was at least the excuse, back then, that we could not yet document the long, hideous reach of the Gestapo. But all the data needed are here already, about the success of the insurgents and the corresponding inertia of the faithful of Iraq, an inertia that issues from a combination of fatalism and fear. The Iraqi who protests and documents an act of the insurgents runs the risk of being the insurgency's next victim.
Here is an important objective of the organs of moral concern. They can't be successful without the cooperation of the Sunni and Shiite leaders, who bear an enormous responsibility to protest what sometimes seems almost a matter of indifference to them.
