Its easy to kill individuals, particularly when you have the satellite support of the USA. What is impossible to do is kill the Palestinian peoples desire to regain their country. After all we should remember that before 1948 when a minority of eastern european colonists together with western military support declared that Palestine would now be called Israel, it was called Palestine, a country with a 4000 year old history. All they have succeeded in doing is create more people around the world and within Palestine itself who hate them. Not much of a success in my view.
