Do you mean it should just let itself be smashed to pieces bit by bit by suicide bombers and rocket attacks and not try to defend itself by cutting off the head of the snake before it strikes.

No, that is not what I mean at all. If Israel will end the occupation of the West Bank, and East Jerusalem, and leave the Palestinians in the West Bank, Gaza, and East Jerusalem alone and let them get on with building their country and living their lives, the problem will go away. The head of the snake is dispair. You can't cut that off. The only way to make it go away is to remedy the situation that is causing it.
