There are hospitals in Gaza. They now have no water, electricity, or communications. People who are not combatants are, without a doubt, dying in those hospitals for lack of adequate sanitation or means to power medical devices.
As I’ve said before, I don’t have good answers, but I do know that punishing an entire population for the acts of a few is generally unethical, immoral, and cruel. Letting hospitalized civilians die is just one example.
