I was asked what should we do. First and foremost, stand up and be counted and perhaps explain your reasoning..or not.

Ask that the "right to exist" be replaced with "de facto existance"..there is a country that acts as a country, that conducts business etc...and that can be acknowledged without admitting to rights, wrongs, etc. This should be standard for other countries too.

Insist on proper water rights.

Insist on borders.

If there must be a "no man/woman's land" insist that it not be filled with settlers, but with orchards, common grounds, parks, community colleges, mutually used theaters etc.
