How many nukes does Israel need to effectively defend itself against the Muslim world? A couple may already be programmed for delivery to a place on the Red Sea and Muslim mindset will be radically changed.
My advice? If you have to 'do' one, might as well 'do' them all that are within reach. Otherwise, Obama might get back from his golf game and throw a wrench into the mixture.
