The chant 'Palestine will be free, from the river to the sea' is a bit of a problem. It has different connotations depending which group uses it. AFAIK it originates from the Arab world wishing Israel to no longer exist as a state, back to an Islamic state. I don't believe that means eradication of Jews per se but for the state to no longer be a Jewish state (however there is 100% groups that want them completely gone). But i think a lot of Palestinians have come to the conclusion that it's not a realistic dream for Israel to no longer exist, but just for Palestinians to be free & able to move throughout Israel as free people and not stuck in Gaza or the West Bank. HAMAS had offered a truce back in early 2000s (whether that is credible is debatable) for Israel to move back to the 1967 borders and Israel to be recognised as a state globally. I just don't think that is a possibility now, the best that could come out of it is Israel being a Jewish state but recognition of Palestinians to be Israeli citizens & being allowed the same freedoms anyone can get. Things like BirthRight would need to be changed as well IMO, as well as re-education from both sides.
