No matter how much you say thing slike that doesn't make it true. There is no sane strategy that involved having millions of hostile people, your enemy, *inside* your borders where they can do harm.
Is it better if you have no control over them and they are free to gather whatever weapons they want, to shell you at will etc? The idea would make sense if the Israelis really did separate from them and respond to any attacks with brutal resolve. The reality is that they not only are not going to separate but that the hostile enemies are going to get a free corridor through Israel. That plus the extraordinarily timid response to the now routine shelling of Israel (free shots until they hit someone and then a show of force and back to appeasement) is nothing more than retreat and appeasement in the face of terror.
