Palestinians aren’t very well liked throughout the Arab world.
Just ask Jordan....................
Or Lebanon. What's left of it.
Anecdotally, I have heard that Palestinians are kinda considered (along with Somalis) to be the trailer trash of Islam - deadbeats, complainers, malcontents, etc.
Much of the Arab world has paid some lip service and money to the Palestinian cause - but all in all, I got the feeling that they wouldn’t be upset if the Palestinians went away and got on with their lives.
