Im not Israeli and im confused. Who owns the land? What does "land-expropriation" mean? "compulsory purchase" or some kind of feudal state allocation, Is the State buying it and giving it free? Is it State land? Is it private land? Do "Jewish" towns have boundaries? Do "Arab" towns have boundaries? or do Towns have municipal borders where anybody (with money) can live and by a house? There are far to many assumptions in this article for Non-Israeli to understand.
