Three years ago the Palestinian-Arabs pulled out of Peace Talks with Israel. They complained when Israel built needed apartments in the “West Bank” and East Jerusalem, despite the fact that Israel had captured both areas in the 1967 Mid-East war. The other 21 Arab states won’t assimilate or support them and want them to remain perpetual “refugees,” for political purposes.
At the United Nations meeting, in late September, Palestinian-Arabs are expected to request recognition as the region’s 22nd Arab state. They plan to demand a return to pre-1967 “cease-fire lines,” where the tiny Jewish state of Israel stopped the aggressor Arab armies in 1948.
For the next 19 years, the West Bank and East Jerusalem were illegally occupied by the newly formed (1946) Arab state of Jordan. Before that, the “disputed territories” were controlled by the British Mandate of the League of Nations, following the WWI break up of the Turkish Ottoman Empire, which had ruled the area for 400 years. These are the historic, Jewish regions of biblical Judea and Samaria, re-won in an unwanted defensive-war, over four decades ago.
In short, there has never been a historic, Palestinian state in the Middle East. There are no “borders” to go back to. The entire area west of the Jordan River belongs to the Jewish state of Israel.
