You have to look at the source of the problem. Two stateless people were offered the opportunity to build an independent nation in 1947, Israel chose to build an independent state and Arabs chose war to gain everything and they lost. They chose war several more times and they lost each time and each time the loaf get smaller as a consequence of initiating wars.
Had Arabs accepted the 1947 Partition Resolution, they would be celebrating 75 years of independent statehood today, with pre-1967 borders.
