People keep saying this but I don't know why. For me it's obvious that if the IDF keep besieging Gaza, Hamas will eventually have to come out of their holes, and die.

I suspect this already happens a lot except we don't get to find out because there's no reporting from the locations where IDF and Hamas fighters exchange fire. But, reports from the few hostages that have been released, or freed, make it clear that Hamas is subject to the same deprivation of food and water as the rest of Gaza (the hostages tell stories about the poor quality and amount of meals they shared with their guards) and they're stuck in their bunkers to boot, which can't be great for their overall physical and mental stamina.

This is not a war that Hamas can win, not even survive. Not in the long run. Their best chance is to keep their heads down and wait it out. But if I understand that, IDF commanders certainly understand that and they're not going to go away until Hamas all come out of their holes exhausted and starved waving little white flags.

I think the mistake people make is to think of Hamas a bit like the partisans who took to the maquis in WWII, or maybe the Taliban against the US. It's not the same situation. Hamas has nowhere to go. They are trapped, like rats in a maze. They're not getting out of that alive, unless the IDF is forced to withdraw by political pressure, which so far is not happening.

Besides which, if the IDF keeps at it like it is, it won't really matter because there won't be any Gaza, or Gazans, left for Hamas to control.

Hamas (and I mean the Al Qassam brigades) are toast. The only question is how much Gaza will bleed until they pop out of the toaster.
