Both Jews and Arabs rejected the Peel Commission report in 1936-37 to partition the mandate and transjordan into a Jewish and Arab state. The Arabs rejected the partition plan in 1948 partly because it would have given the Jews 55% of the mandate palestine while they were only 30% of the population and it would have included 407,000 Arabs living in the Jewish state. As for the Barak generous offer myth, acc. to the Oslo Accords 1993 Palestinians agreed to accept 22% of the historic mandated Palestine, with Israel having 78%. Barak disagreed and proposed that 69 colonies populated by 85% of the colonists would remain. Palestinians would thus be required to relinquish another 10% of their 22%.Then Barak demanded something called "temporary control" which would have deiminshed the area given to Palestine even further. So go back and check your sources. This generous offer myth is nothing but zionist propaganda. According to the Saudi proposal, there is leeway in discussing the refugees.
