It seems a shame that Palestinians and Jews cannot peacefully exist in one, united country

They can peacefully exist in one united country. While it's not yet a country, there are non-Jewish Palestinians and non-Palestinian Jews living together in Palestinian villages in the West Bank. These are not the same Jews as the ones who are living in the apartheid settlements. These are Jews living in together with the Palestinians in Palestinian villages as equals, and not as occupiers. What the Palestinians are not able to live with is apartheid and military occupation.
