Well, there are ways to end it. Historically there have been thousands of cyclical conflicts that eventually ended without a diplomatic solution.
But, I think its reasonable to assert that the Arab world desperately needs to become more secularized. Most of the Arab world is deeply anti-semitic, deeply tribal (even amongst themselves), and deeply backwards in their orientation to what makes a free society possible.
In that sense, the palestinians need a big cultural change.
That's arguable, certainly in the west at least. Even if most people oppose the current war/atrocities that doesn't mean that they generally favour Palestine (or especially Hamas..) over Israel (.e.g. like you didn't have to be pro-Sadam to oppose the war in Iraq).

You probably don't know. Neither do I. If we did, other smarter people would have too and it would have probably been implemented already.
The money from Qatar had humanitarian goals like paying government salaries in Gaza and buying fuel to keep a power plant running. Obviously, the money was misused and spent on building rockets and missiles. But also a portion was spent on what Qatar intended.
The rationale at the time (this was not a secret deal or anything like that) was that Qatar money is going to make it to Gaza one way or another anyway - it's better if Israel knows about it.
And somehow throwing Netanyahu into the mix is just meant to have some people see red. He was out of power for a year and a half. Surely if it was his personal agenda, the govt that took over after him would stop the payments. They didn't.
But I agree with you that no matter how you twist it, it's definitely a blowback.
(I also strongly disagree with calling it a genocide, btw.)
