Many jihadis were/are buried under the rubble. With the war taking at least another year, many body parts will be decomposing even further. There are probably some non jihadis as well underneath the rubble. And perhaps a few hostages.
Then there are probably all of the above also within the collapsed tunnels. In the sense of lessons learnt:
-Israelis will not be so complacent as they were before 7Oct2023 … and will track better the jihadis.
-Gazans will not be so complacent as they were before 7Oct2023 … and will avoid better the jihadis.
-Gazan jihadis will have less trust in the fast talking Hizzybillies and Mullahians.
-Gazans will be avoiding the Captagon short-cut to courage.
-Israelis will increase their DIY weapons production.
-Israelis will require mandatory latrine duty for those Unsettling Settlers.
Etc. etc. etc..
