You are correct I did not read that part it is far down.

Your suggestion is still misframed becauses Palestinians believe it is impossible and will never happen too. Even in your link:

At the same time, 58% believe the two-state solution is no longer practical because of settlement expansion

A two state solution has been rendered impossible because it would only work by expelling all the colonists that have stolen Palestinian land in the West Bank.

Most Palestinians would prefer the knee of their occupier of their necks rather than having to die for full restitution of their rights. That is why they would be willing to concede some land. But that does not change that all of Palestine still belongs to them.

There is no reason to start off from a softer position in international politics than demanding all that belongs to Palestinians be returned to them unless Palestinians make a deal with Israel to divide the land. Israel is currently in a position to do that but unless they are under pressure they will never make such a deal. One should not concede that Israel has the right to any part of Palestine as a starting position.

If Israel fails to make a deal while they have the upper hand then their right to any land entirely falls off.

If you oppose Zionism then you cannot start off from the position that a racist genocidal ethnostate should exist next to Palestine. Do you think Palestinians would want a two state solution if they gained the upper hand militarily? As if Jews wanted a Nazi Germany right next to them.
