“The Biden administration warned that an attack on Rafah could cause civilian casualties there.”
They aren’t civilians.
Well, this could be a good thing. We know that 70% of gazans voted Hamas into power and cheered on their rape and murder. We also know that UN lies routinely about pretty much anything. So, I suggest that the real number is ~400k. That might, let’s try some optimism here, be the 30% of non-monstrous gazans that ought to be getting themselves out of the war zone started and sustained by their neighbors.
So, that means that the ones remaining are all Hamas and their supporters.
Free-fire zone for IDF. Shoot everything that moves and make sure they will not need an ambulance.
