It’s going to take years, if not decades, to clear the rubble and the human remains still inside.
The millions of reconstruction for billions worth of damage will ensure there is maximum amount of ‘unpopulated’ Gazan area for Israel to remain occupying.
Which also means there is a baked in flashpoint of conflict where Israel will have to leave areas that are rebuilt. The entire history and existence of Israel indicates this will not happen: settlers will occupy anywhere the IDF is: which brings us back to the status quo.
