How has Hamas survived this long?

Since the October 7, 2023 atrocity when Hamas killed 1,200 Israelis and captured 250, the terror organisation has suffered a huge death toll at the hands of the Israel Defence Forces (IDF) - perhaps 17,000 kiled - and have lost nearly all of their top commanders. And yet, somehow, Hamas still survives both as a fighting force and as rulers of Gaza. How is this possible when Israel has the military power to annihilate them? It's yet another golden rule learnt by the superior of two military forces, that might and firepower don't necessarily bring victory. The Taleban survived against the huge superiority of the US-led coalition forces over 20 years because it was their territory, they knew where to be, where to hide, and how to fight a superior force. The same has been the case with Hamas versus Israel. Hamas still have their underground tunnels and bunkers, they have the remaining Palestinian population to hide amongst and when their commanders have been killed - the latest one killed this week - they bring on new ones. Benjamin Netanyahu wants to destroy Hamas once and for all. I don't think the IDF are ever going to be able to achieve his objective.
