Israel agrees to absorb 6.4 million people into a population of under 10 million (including members of Hamas),
I mean yes. Those are the descendants of the people who were displaced by Israel, and they have a right to return to their homes.
Israel has offered Palestinian leaders nearly every inch of the land of Palestine, but every offer has been rejected by the Palestinian leaders.
That's misinformation. It's a pain to list all of them, so if anyone bothered to read this far and is curious about why any specific offer failed, just ask. Hint: The answer is usually that Israel, not Palestine, refused to compromise.
