And its targeting has sometimes been imprecise, and has shown a casual disregard for the lives of Arab civilians.
I think the casual disregard for anyones life is what the IDF are trying to stop. Everyone seems to think that it is now possible to plant a GBU/LBG right into the car of a terrorist and not kill the other passengers. This just isn't the case. Personnaly, I think they have done as well as they could have to avoid hurting innocent lives but only in as far as they are able to do so. Alot of the munitions being used have a very small warhead in order to avoid collateral damage and death.
When the Palestinians stop blowing up restaurants and buses then maybe the IDF will have no cause to target in the "occupied territories"!
