Many Palestinians were against Jordan rule of Palestine. But let's assume what you are saying is true. The simple answer is: Jordan gave Palestinians citizinship and it treated them like normal citizins. However, Israel does not give Palestinians citizinship nor any political rights. which makes a huge difference... What you are saying regarding Jerusalem and Mecca is total nonsense.. because Jerusalem is the home of so many Palestinians who should have the right to live there and enjoy their civil and political rights.
