Subject: Re: Hamas launches mass attacks on Israel
Worth noting the UN Plan also called for the creation of a Palestinian State. The Israeli's accepted the plan basically agreeing to live peacefully next to a sovereign Palestine. OTOH, the Palestinians rejected the Plan and soon after helped launch the six day war where they and the rest of the sneaky Arabs got the butt kicked and were driven off the land that would have been Palestine. Over the years, Israel has given back some (most?) of that land in various land for peace deals,. deals that the Palestinians inevitably did not honor.

Yup, this. You added some of the most valuable context of all.
The Palestinians displaced by the formation of Israel listened to the likes of Egypt's Nassar and King Abdullah of Jordan who convinced them they could join forces and drive the Israelis into the Mediterranean. That didn't happen - the combined Arabic armies lost - and with that loss the Israelis were in no mood to entertain anything.

During the course of the war some 750,000 Palestinians fled Israel in the Nakba; at the same time, many Jews were expelled from or hounded out of Arab states.
