Given he was the Hamas negotiator, it certainly shows Netanyahu and company have no interest in negotiation and likely see more war as necessary to maintain their increasingly isolated global situation, as well as ride the Zionist tiger.

In which case, the best move by the Irans would to make a huge issue around Israel's incorrigibility at the UN, to the point of organizing a walkout, under threat of having to expand the war otherwise. While talking up a BRICS version of UN, if nothing is done.

That way,it throws a huge stick in any remaining pretense of Western moral authority.

Which would seriously give Iran the moral high ground in a way all the propaganda and biased coverage couldn't hide.

Though it just looks like more war.
