And Arabs have been trying to attack Israel ever since it was founded and didn't have much success with it. By now they all know it's futile and all they are trying to do about it is to handle this situation in a way that does not infuriate their own populations too much so they can stay in power - Israel understands their difficulties and is willing to help - they also don't need all Middle East to throw itself into chaos with governments falling like dominos, again - that's the only reason they are still so indecisive with the "Palestine".
