They have not learned they have to stop talking and telegraphing what they are thinking rather than just doing it. If they had moved full out on Rafah it would be done. Now that window is closed.
The window is not closed. They act the way they think they should and not carpet bomb civilians. Plus, they made the choice to push all the civilians south first, to clear north Gaza. Now they have to push them east and north to clear the south while they clean up Rafah. Which they are doing. My guess is they won’t agree to complete withdrawal they will want to keep the border with Egypt and some tactical strike positions.
I don’t know if they are telegraphing to Hezbullah per se. I see this more as a warning. Gaza ops will wrap up soon, and then a militarized and angry Israeli populace won’t put up with continued attacks from Lebanon. Might as well get it all cleaned up if they are on a war footing. And they will bomb the heck out of Southern Lebanon. Nothing compared to Gaza.
