What is a life worth?

When we listen to Israeli officials talk about the Lebanon’s civilian deaths they don’t seem to think Arab lives are worth much, certainly not as much as Israeli lives. The Israeli’s seem to think to destroy Hezbollah is to kill as many Arabs as possible. But it is human nature to value your national Citizens more than whose of other nations. What about the Arabs themselves the Hezbollah and other much groups came up with the suicide bomber that targets civilians, kills a loyal supporter of the Group and usually turns public opinion against them. The Hezbollah rockets seem to be more like World War two rockets that you just fire in the general direction of your target. When it runs out of fuel it comes down usually killing civilians.
It seems to me that both sides should have figured out by now that they can’t wipe out the other side and there for must come to some kind of an agreement. I am just a common old working lad, but I seems to me that they could come to that agreement before they started killing civilians most of who are children.
Then there are the young people that risk and sometimes give up their lives willingly sometimes for a lies told by their leaders. Just because these young people want to be heroes does not mean governments or any leader has a right to take their lives unless they tried everything else and there is no other way.
