Yes, but I don't understand how carpet bombing protects them or helps them rescue hostages. They will still be in grave danger if they enter gaza, perhaps even more danger in this environment. It's hard to pick out any military doctrine that suggests otherwise. This has been a repeated criticism of this type of military activity, across campaigns all over the world and recent history. I supposed you could compare it to allied bombing of axis forces, but I would argue that those campaigns were carried out as part of a much more stringently determined military strategy, rather than as a per reactionary action.
