Taking palestine back would not mean such atrocities would have to implemented on the jews. They might stay and be good citizens or go back to wherever they came from. but this is a very long term perspective.
Israeli so called nuclear option is totally and utterly useless. They can bomb the whole muslim world. They can kill 1 billion people, 1.5 billion people but in 50 to 100 years this embers will recover. nations will rise again. But they wont. If they start a nuclear armageddon, the whole world that is left will chase them down.
They are not that stupid.
Obviously the only way to prevent them even thinking about this is for the oppressed people of earth to develop nukes. Without nukes this will keep happening and that little boy running after his dead father will continue to suffer with more and more such little boys.
Every democratic muslim nation needs nukes yesterday. Turkey, Indonesia etc. to stop this heartless slaughter. Either that or move the palestinians to somewhere safe until the nukes are ready.
