If they could formulate a strategy to kill 0 civilians, and minimize IDF casualties, that would absolutely be ideal.
Civilian lives expected to occur, but not in exponentially higher numbers than terrorists. So in a special forces ground attack for example, there will still be some civilian casualties. Perhaps a teenaged boy is frighten and runs to a bedroom and is shot by a special forces agent thinking he was going to get a weapon... This is absolutely understandable.
I just don't think a strategy which yields more death of children than terrorist is fruitful or viable unless you have a different agenda that you're stating.
