HIT the target
I would think anything in the Gaza Strip is the target.
You can’t win a war like this. And where is the psychology. Hit all the targets and when the media accuses Israel of killing children, instead of trying to explain that Hamas uses children as shields, say in a sneering tone that Hamas has to learn that they make poor body armor or missile armor. If the world does scream much louder than usual, at least that means at least they are out of their typical Jew hating comfort zone.
