All the whining about "stolen land" is just piss-poor propaganda.
There are no "Palestinians" even, just some Arabs who originated from Egypt and Jordan, sitting on their asses, getting money, food and education from UNRWA and making kids, many many kids.
It is good that Trump is finally stopping that nonsense.
Let's put it this way; I believe you about the origins of many Palestinians-although there have always been quite a few Christians, Muslims, and Samaritans in the Holy Land, Bedawi, etc... More were migrants from the rest of the Muslim world during the Turkish rule and later. In the Middle East most identified until recently with their religion, their locale, their tribes and families and clans (which I think is the most correct attitude, btw), not Nationality.
But Today, there are many who DO identify as being Palestinians, and the Jewish State MADE THEM AS SUCH, by it's combination of both liberal soft-headedness and misplaced compassion, and sickening brutality and torture....
For God's sake either push them all out, those who identify as Palestinians anyway, or give up on the inane quest for a ''Jewish and Democratic Nation-State'' which in context is a contradiction in terms.
But man is a fickle and disreputable creature and perhaps, like a chess-player, is interested in the process of attaining his goal rather than the goal itself.
