What would be a 'proportionate' response to hamas by Israel?

Well this whole mess goes back too many generations for it to even begin to make sense any more. All I know is that we are dealing with two very proud groups of people who don't react well to violence. That being said, they are ironically violent towards their enemies. There in lies a stale mate. Until they can BOTH figure out a way of discussing and compromising then the world shall continue to see further horror in one of the most sacred and beautiful parts of the world.
