Actually Israel has a shit ton of bulldozers and combat engineers clearing rubble over the weekend. There’s a lot of video.
It’s also fixed the pipes and cell network and is flooding more aid than the rest of the world combined into the war zone including fuel. Under guard.
They do it because they are providing aid too.
The cynical reason is they are confirming targets eliminated.
The IDF didn’t need to fix the cell network, or the water pipes. The former directly hurts them.
