As to how to react, we have a choice. We can express justified horror; we can seek to understand what may have led to the crimes, which means making an effort to enter the minds of the likely perpetrators. If we choose the latter course, we can do no better, I think, than to listen to the words of Robert Fisk, whose direct knowledge and insight into affairs of the region is unmatched after many years of distinguished reporting. Describing The wickedness and awesome cruelty of a crushed and humiliated people, he writes that this is not the war of democracy versus terror that the world will be asked to believe in the coming days. It is also about American missiles smashing into Palestinian homes and US helicopters firing missiles into a Lebanese ambulance in 1996 and American shells crashing into a village called Qana and about a Lebanese milita--paid and uniformed by America's Israeli ally--hacking and raping and murdering their way through refugee camps. And much more. Again, we have a choice: we may try to understand, or refuse to do so, contributing to the likelihood that much worse lies ahead.
