Remember, the enemy WANTS to lure us into a "Jenin Massacre" situation. That's their GOAL. They will be thrilled if we kill 100s of them, if they can only kill a few dozen of our Marines, and film their bodies in the street.
They will be even more thrilled if we accidentally cause patently innocent civilian deaths, especially women and children. In fact, they will blow up their own women and children, if they can blame it on us. And those "burning baby" pictures will be THE pictures that are remembered, no matter who torched the kiddies.
That's why the IDF pits their strength against their enemy's weakness. Pay good $$ for good intell on specific enemy leaders, then kill them from the air. To me, this is preferable to giving the enemy their desired "Jenin Massacre" TV footage.
