I don’t see why they’d need to occupy anything. Occupation would imply that you wanted to control that area and those people. I think Israel knows occupation would never work and wouldn’t try it. They’ve preferred to wall-off people in enclaves, slowly squeeze all life out of those regions, and when the people they have cornered inevitably violently lash out against their own slow-motion genocide, it’s time to flatten the area with bombs again. Israel calls it “mowing the grass” and I don’t think a massive occupation fits with that strategy. I think they want to break the region, scatter the people, and leave it to rot, not occupy and be forced to manage it into the future indefinitely.
