You think 200 some hostage will stop the Israeli from invading Gaza, well, that's your first mistake.
It wouldn't take a military person with military background to know this is just not going to happen, a no-go from the get go, I said even before Israeli stack its card back in mid-October this is going to be a go and this is going to be a slaughter inside Gaza. Then people like you laugh at my post, and well, we all see how that go.
On the other hand, this is a conventional warfare, like it or not, at least IDF is playing it conventionally. Just because Hamas chose to fight unconventionally does not change the dynamic, because this is not a Hamas operation, this is IDF operation, and if IDF choose to fight street by street, house by house and block by block, then this WILL remain a conventional war, because how Hamas offer their resistance is largely depends on how Israeli attack. It's a common misconception that you can't fight asymmetric warfare conventionally. Again, that's really depends on the attacker's tempo, if they can keep the tempo in a conventional way, that war will remain conventional, but if they can't and the dynamic shift, then they will need to adapt and either do COIN or lose that war. The thing is, IDF already said they have no intention on staying in Gaza, which mean they really don't need to consider the COIN/Insurgent part, which mean they just need to focus on how to dismantle Hamas resistance street by street, house by house and block by block, destroy the HAMAS network and go home like they said, before any counter attack even materialise.
