What would be useful is a historic example where another approach has worked. I don't approve of Israel's methods. I'd prefer an egalitarian solution. But, I'm all out of ideas. Find me an instance of 2 co-habiting or neighboring groups that hate each other, have huge disputes and ended up in relative peace.
I can give you my recent examples of previous instances that are now mostly peaceful, and all of them violate the geneva convention or UN human rights declaration.
Xinjiang = permament open air prison and extreme brain washing
Srilanka LTTE = violent genocide of all suspected participants and their innocent family. 100k civilians killed
Bosnia - Sijekovac killings = violent genocide of thousands of innocent Bosnians in the Bosnian war
Kosovo - thousands of killings, massive population displacement (1+ million) & US military intervention
So what is it ? Do we want the US to intervene and guarantee safety to Israel ? Do we want real open air prisons and complete cultural eradication ? Do we want population displacement of every Gazan to a 3rd location ? Hopefully we are not in support of genocide ?
Well, so what is 'another method' ?
Every single instance of haphazardly drawn post-WW2 line, has led to some kind of insurgency, war, genocide or forced population displacement. Peaceful borders are drawn in the blood of ancestors. The west is simply fortunate enough to have concluded it's killing mid-way through the 20th century. Israel is currently going through one such process. It is especially rich to see the criticism come from western nations who first created the problem. They encouraged the conditions that led to Oct 2023: 2005 withdrawl of Israel and rise of Hamas, and its unilateral control on aid. They refuse to propose any middle ground solution. It's ridiculous.
