Camp Davis and the Oslo Accords were a way for Israel to change the De Facto annexation of the West Bank into a De Juro annexation. While giving the PA a 'semblence' of a state still under Israeli Military Control. There was no offer of a sovereign state, nor of right of return. Arafat didn't reject a Two-State Solution, he walked away from a verbal 'offer' of taking 90% (later ~80% once written up in Oslo) of the Occupied Palestinian Territories, while ignoring all Palestinian wants such as Right of Return and Sovereignty with an end to Occupation.

If Arafat wasn’t serious about negotiations, why sit down at all and risk his position in the PLO? For decades the ‘Three Nos’ stunted any Arab-Israeli diplomacy, and the maximalists still hold sway today as they did then

Israel refused the right of return for Palestinians as a whole, while for decades doing all within their power to boost Jewish immigration, bankroll Aliyah flights, rubber stamp naturalization, and regular ‘missionary’ trips to visit US and European nations - all only for ethnic Jews, and their spouses.

A two-tiered system based on race is hardly a fair deal, especially in a democratic system where your people are denied fair representation whilst Jew from the world over are invited to jump on a plane and become a full citizen after three months

Every offer has been in bad faith, though, designed to be a non-starter so that Israel could claim they tried.
