Couldn’t the Palestinians have had a state if they had agreed to the original ’48 partition which WAS a two state solution? THEY chose to fight and not accept the Partition plan, the only reason a “two state solution” is on the table (as opposed to a “one Palestinian state” solution)is because they cannot crush Israel militarily! You can’t attempt to crush Israel , then when you lose insist that you would still like to crush that state and then expect Israel to be OK with giving you control over a bunch of land.
As an aside Arafat tried making an uprising in Jordan before he really started with Israel. Arabs are a whole lot meaner to other Arabs then the Jews are and the Jordanian army smashed the Palestinians so hard that it would have made what happened in Gaza look like a water fight.
