In general, no. But I take the chant as evidence that lots of people in Iran would be happy if an atomic bomb went off in New York City. If someone says he wants to kill me, I raise my estimate of the likelihood of him wanting to kill me. If he says it over and over again to his cheering friends, I fear him and want him to be weak even if in the past I have given him justifiable cause for offense. I become really, really scared and desperate if I think he would be willing to kill me even at the cost of giving up his own life. I wish my president shared this view.
