But Pat, the atrocity propaganda drums sound too loud for us to hear reason. In this Iran obsession we have something even worse than the usual atrocity propaganda: imagining how a suicidal Iran might use nuclear weapons is used to justify another un-winnable war.
I saw a video of hysterics imagining that Iran, if nuclear armed, would detonate it over the central US so the electro-magnetic pulse would shut down our power grid.
Generally atrocity propaganda just makes exaggerated claims about what the boogey man did: this time we hear what he could do. We are doomed for our own hubris, not Iran's policy.
