Yep, have to contain the feedstock for extermination.
Anytime, IDF can kill 20+ for a loss of one, they'll keep going. Building a Greater Israel one dead Arab at a time. After all, there's nothing wrong with settling desolate land. If the Arabs leave Gaza voluntarily, that's OK too. Better PR, but less satisfying.

"There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
-- Isaac Asimov
