Frenkly do not know what is end game of this operation but if some news are true that israel asked for truce already via egypt mediators it is huge win for them.
Also, some unconfirmed rumors that they managed to reach hebron in west bank, that is other significant thing for them to gain even more popularity among palestinian people and show that armed resistance works at the end.
First of all, I don't see any report anywhere from either side showing they went as far as Hebron, that's another part of Israel, which would require another front, and that would be a big news because you can't hide the other front. You would know if Hezbollah have entered west bank whether or not they have taken Hebron.
Second of all, I don't think it's likely that Netanyahu would back down just 1 day after the attack, if so, that either mean the Israeli weren't ready at all for this attack and this attack should have and would have progressed a lot further than it actually did, or Netanyahu just lost his plot. This is not really a big scale attack, that is within the coverage of the IDF to recover those area, I mean it literally would have no meaning to ask for a truce now, for what? They mobilise for reserve and then ask for truce?
And finally, there are always end games with these type of attack, you don't just wake up one day and tell yourself you need to kill some Israeli today, something HAMAS wanted from this, the question I ask is what is it that they are looking at, and how is this attack going to contribute to their plan, and if they are, like you said, have no end game, then this attack, or whatever this is, is doomed to fail.
