Why do Palestinians claim that theyre the victims when they rejected a two state solution proposed by the UN in 1947 and have since rejected every other solution Do they really want a separate state or do they want ?

Palestinians were the majority and owned more than 90% of historic Palestine.
While publicly the Zionist Yishuv accepted the partition plan, it did so as a temporary tactic only. In private, they rejected any idea of partition and quite candidly admitted that partition would be a means to establish a strong army to take over the rest of Palestine.
While addressing the Zionist Executive, Ben Gurion emphasized that any acceptance of partition would be tactical and temporary:
“After the formation of a large army in the wake of the establishment of the state, we will abolish partition and expand to the whole of Palestine.”
