Fine. Let them be replaced in due course by a legitimate form of government that is fairly elected. Sounds great to me.
You know I don't see Gaza as an illegal occupation. I did before October 7th. I find the settlements in the West Bank to be still illegal.
In my learned opinion though, after October 7, Israel has good and just cause to go to war to eliminate Hamas, the de facto government-in-hiding of Gaza, and its tunnel network. Hamas is not a legitimate government and can simply no longer remain in charge, dead or alive. I don't see anything illegal about occupation, the goal of which is to achieve that end, because n so far as Gaza ever was a state under Hamas, it is now a collapsed state with no effective government, legitimate or otherwise. It's a rump state. Irredeemable territory. And, in that case, it's the neighbor's duty to step in, establish law and order, and govern temporarily, legitimately and equitably.
Martial law is a legitimate form of interim government during a transition from hot war to reconstruction, before a provisional government of local stakeholders can decide how to form and choose a new government. No government run by the whims of a few religious people will ever be legitimate.
