What about the Jewish people of the land? Do they have a say?

In the most extreme case, you get a village-by-village, street-by-street or house-by-house subdivision of the resulting countries.

Of course this doesn't really work very well, see Bosnia.

No. I would say that the most extreme case would be just 0 Jews. We in fact saw it across Middle East already.
