That is what they say but is it the case?If they have a plan to move civilians then they won't be killed.
I have no idea whats in their stockpiles, but the fact that they were being replenished tells me they need more. If they know they aren't getting more, they need to ration them and put Israeli interests over palestinian civilians interests when deciding where to use them.
The UN said they aren't moving, do you think every last civilian will leave before they launch an offensive? Additionally, with the amount of pressure the US os applying, they may need to move fast and not leave enough time for all civilians to evacuate.
