Bro, I am sure that most of the Gulf Arab population are decent and good Muslims.
It is unfortunately natural for wealthier people to think they are "superior" to those that are less wealthy.
What is absolutely not in doubt is that the Gulf Arab leaders and the Jordanians have sold out the Palestinians for sure. With Egypt they were suffereing tremendous economic difficulties due to the loss of the oil fields in Sinai and revenue from the Suez canal and so it is more understandable why they had a peace agreement with the Zionist entity.
Palestine will one day join the rest of the nations of the world as an independent and proud country. Your time will come.
