Mr Myer: an area without a legally constituted existence or legally constituted rulers because no-one had the proper authority derived from 1917/22 so to constitute.

It might be a good idea if what is now intended to be called Palestine, and what is now called Israel (or a smaller area, like for example the 1947/8 area) were both recognised by the UN and (a separate issue) by each other. I don't offhand see how Palestine could (lawfully) continue its opposition to the existence of a state of Israel if it was a member of the UN (because it WOULD then have "joined the club") - and I don't offhand see how Israel could (lawfully) continue to occupy and oppress the West Bank and Gaza and their occupants.

I suppose they could (like the USA) say "OK, have an International court so long as it has no jurisdiction over me", but I haven't noticed that being said yet.
