Israel has signaled once again that it is weighing an attack, if all else fails, to halt Iran’s advancing nuclear weapons program as an act of anticipatory self-defense. This time, more officials in Washington and other capitals are listening. Iranian officials have repeatedly warned that Tehran will retaliate against the U.S. in the event that Israel launches a strike. The U.S. should have a clear and unambiguous policy on how it will respond if Israel undertakes legitimate action for its self-defense.
