Hamas is a response to Israeli violence and colonialism for the last 70 years. You can depose them but another group will rise up with arms to resist colonialism as long as Israel keeps doing the same thing. And they did before Hamas, so of course they will after. Plus, it will be even harder as these events drive recruitment for Hamas. America didn't get rid of the Taliban by bombing Afghanistan for 20 years, either. It doesn't work.

Israel has been occupying Gaza the whole time despite their rhetoric. They control all their infrastructure and built a big wall to keep them in, and control all travel in and out, plus they constantly spied on them with everything from drones to listening devices to taking random hostages and trying to get info out of them. Gaza doesn't have control of their own food, power, trash, travel, water, sea territory, money, etc. That's basically an occupation, no matter what they say. The only reason to need to take it a step farther and put troops on the inside instead of all along the wall outside is so they can kill more Palestinians.

The scare tactics of claiming they'll never be safe is how you get a genocide, both now and in the past. It's that thought in WW2 that leads to rhetoric like, "We tried to let them live in peace with these stars and putting them in their own spaces in towns, but they keep causing trouble. They even want to do a Warsaw Ghetto Uprising over and over again. We're going to need to kill all the Jews, it's just the only solution."
