That really is the problem. Both sides suck in this war.

On the one side we have a colonial apartheid regime that tries to steal every inch of land while imprisoning the native population in ghettos and restricting their economic and human development and trampling their human rights.

On the other side we have a desparate population seething with righteous rage at their oppression that has rejected every attempt at compromise and is only willing to stop once they have fully driven off every last invader off their land, but realistically they don't have the power or international support to achieve that, and they also never owned every inch of the land, either. So. Their ambition is neither realistic nor righteous.

While most Israelis are European colonists who could migrate to either Europe or America, not all of them are and it would not be fair to those whose ancestors lived in the region for hundreds of years to become refugees.

So anyway. I think the EU, UK, USA and Arab league need to come up with a reasonable plan - in consultation with the Israelis and Palestinians - and just force Israel and the Palestinians to accept the most reasonable plan. Both groups are fully dependent on their benefactors, while their domestic politics prevent them from solving it without external pressure.
