Please correct me if I'm wrong. To me, a preemptive strike is striking before missiles go flying from Iran to Israel. I don't believe that Cain said he would strike Iran before they struck Israel. Don't get me wrong: I do like his stance on Israel, but I don't think he stated that he would strike Iran first -- which, again, would truly be a preemptive strike and one that, in my opinion, is needed, Hashem willing.
