micro, cant confirm but common sense dictates.
This won't happen, but imagine Hamas wanting to buy in. Let's just say that would not be allowed. Equally, nor would any organization that is not in good standing with Israel.
Zion is aware of this dynamic. Prior to any buy in, they (simply out of courtesy and wanting to retain good relations) would run it pass those Israeli Authorities and the owners of the land they are prospecting on.
Just good business sense.
