Living here in the U.S. I am loath to tell my Israeli brethren what to do. If Israel attacks Iran there will be (non-nuclear) missiles shot at Israel in response. Perhaps hundreds will die, maybe more. Here in N.Y. though, having seen thousands of neighbors die because we didn't take maniacs at their word, perhaps the safest thing Israel can do is neutralize Iran's nuclear capacity to give such weapons to Hamas, notwithstanding the immediate consequences.
