Once you describe one party to the negotiations as illegitimate, you have lost all credibility with the Palestinians. I don't think the Israelis would find that helpful.

Sometimes one party is in fact illegitimate and "negotiating" in bad faith. At what point does one call it for what it is? If one party in the dispute declares the desire for the destruction of the other, is there really room for politesse?

I would say that is up to Israel to decide whether they want to continue negotiations. Anyone familiar with domestic Israeli politics understands that there is significant support for continuing such negotiations and not shutting the door on any future talks. Even Bibi voices his willingness to negotiate—with certain preconditions, e.g., the other side recognizes Israel’s right to exist.
