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.
The Arab countries have given the Palestinians billions of dollars and it disappears into Swiss bank accounts and never gets to help the people. The other Arabs are tired of wasting money.....................
