The problem is they didn't occupy Gaza, it was a ghetto left to its own devices, to occupy it meant to be responsible for it and its people including food aid and social services. If Trump can take over America based on imagined grievances, then Hamas can get elected on legitimate Palestinian grievances about collective punishments forbidden by the UN and a multitude of other abuses involved in driving them from their land and homes.
Israel has little choice but to go in with aground assault and set up camps to sort those in Gaza into while they level the place and dig up the tunnels. I think Bebe wrote the hostages off and it will be full on retribution starting with Hamas in Gaza but not ending there. What they triggered is a response that will last for years and involve a dozen countries or more. Russia is an ally of Iran and was involved in giving captured Ukrainian weapons to Hamas, who even made a video thanking Ukraine for the Russian disinformation operation. This means the Russians were in on it and provided those arms ahead of time to take advantage of the terrorist attack with an operation designed to attack Ukraine funding. I think this will drive Israel closer to Ukraine, the enemy of my enemy is my friend and the Jews of Ukraine seem to be a patriotic lot, supporting their government because it is liberal democratic. Both Ukraine and Israel want to strike a blow at Iran, and both are pretty good at technology and drones so they should come up with something to make the regime feel the love.
