Reading your comments I do not think there is any problem with Jews building homes in the West Bank, I do think Israel should assist in building housing for some Arab populations in the West Bank. Their are also apartments building projects in the West Bank/ Judea/ Samaria built by the PA for housing but many Arabs do not live in them I do not know why but I can further research that.
I do agree that the internal divisions with the Arabs of the Post Palestinian Mandate are very divided in Gaza and West Bank.
Also the many refugee population in the border nations. But going into the future there will be a moment that will unit the Arab world once again for the Arabs of Israel most likely after the War with Iran.
