Exactly how many Palestinians are you willing to kill to stop the rockets? You talk about destroying all of Gaza so I have to assume that you don't care how many people get killed in the process. How long are you willing to maintain a large troop presence in Gaza? You know as soon as the troops leave the rockets will start again. BTW I realized as I read the article that it would probably be fairly easy to make a multi-stage Qassam which would give the Palestinians more range, so are you going to shove all Gazans into the sea to create a "buffer zone?" I think you are discovering the limits of belligerence.
