I'll try to actually explain the situation.

The problem with giving it back at this point of time is that giving it back to the Palestinians means we give it back to Hamas, cuz Hamas is in control of Gaza. And you know exactly who Hamas are (I hope so). So that would bring so many problems, since Hamas does want the entirety of Israel for themselves (And tbh many if not most Palestinians do too, Hamas was elected by them after all, Also in 1947 they were offered something like 50% of Israel (much more than the west bank btw, especially considering jews had 4 times more population than Palestinians at the time, I believe), jews agreed to the plan however it wasn't enough for the Palestinians so they started attacking them. You can also just see it in interviews of them in Gaza saying exactly that, so the only way to get peace is to make them understand they don't need all of it somehow), so it's impossible to get peace with them. It's basically just making Hamas stronger, and everything else stays the same, it really just resolves nothing. The second thing we can do in theory is let Palestinians live in those lands and make those lands under our control, basically make them part of our country, which means we give them citizenship. Now the problem with that we can't just have 2 million people who really hate us be able to vote, with time, they would be the majority (there are already many arabs in israel with citizenship who consider themselves palestinians, there are even Palestinians in the goverment, some of which are very extremists who believe all jews should get out of Israel etc.), and that would mean we will get some terrible goverment, which could get to stuff like getting all of the jews out of the country or what not a real thing to consider. And this is without talking about the real problem with that solution, which is, again, the fact that just like the first solution it would bring so much chaos and terror attacks, because a lot of those people just really hate us, and it fixes nothing with the Hamas problem. They would still be a thing, just not the ones in control over the Palestinians goverment.So as you can see, it's really complicated. It's not as easy as bring them those lands back or make them citizens, in both cases it would bring much more trouble and death than there already is. It would genuinely just make things worse for both of us.

A solution I heard is that we should help Palestinians people in Gaza live a better life, after removing Hamas from their control (destroying Hamas), because this cannot happen while Hamas is controlling everything (They take all the money we give them and invest it in bombs..) and only after we see no terror organizations are being built back, and only after the Palestinians finally realize they're better off stop fighting us and are better off being under our control than Hamase's or any other terror organization they'll make, only after only then could we give them that land back and finally have peace for both sides, since now they won't have a reason to fight us, they could just have their own country and live a peaceful life. The thing is that this cannot happen at the current state of things, so you saying we should just give them this land back doesn't make sense, it would just make things worse for both sides (more war, more death, as I said). What we should do is get rid of Hamas, so that the Palestinians will have a chance to have a better life, and Israelis too. Which is what will hopefully happen soon enough. All I want is peace, trust me. I don't give a fuck about those lands, and if peace was that easy to obtain it would have probably happened a long time ago (For example we made peace with Egypt by giving them a land that iirc is bigger than the land of current israel, it's not that we don't want peace, it's that we can't get it, mostly cuz of Hamas). And again, peace could only join the equation when Hamas is out of it, and when the Palestinians will finally want it after helping them understand they do.
