There’s also this looming issue of what happens with those Gazans that are fleeing into Egypt. Egypt neither has the resources nor political stability to absorb that influx of refugees, and I’m absolutely certain Israel is going to deny a huge chunk of them, if not all of them, re-entry to Gaza when/if the dust settles. Disgruntled refugees plus renewed vigor of the anti-Israel Muslim fundamentalist bloc has the potential to upend things in Egypt, so there’s a big motivation to keep the number of refugees to a minimum.
