That's the closest to an argument you have here.
Is it possible for Hamas to not use hospitals or schools as bases?
The real argument is would it be possible for Hamas to
be able to use hospitals as bases.
Hospitals in Gaza are filled with international aid workers and volunteers, none of those would put up or not report Hamas if they were using hospitals.
That has nothing to do with whether or not Hamas is using human shields.
No, it has bigger questions about the legality of Israel's attack on Gaza in the first place.
As the occupying power they are duty bound to protect the people they occupy, and they do occupy Gaza.
The blockade was already a war crime according to the Geneva Conventions.
The occupation of Gaza is a war crime.
Apartheid is a crime against humanity.
You can't argue in court that you were using self defence to keep committing war crimes.
