If you start with the view that Israel has a right to exist, like Kuwait has a right to exist, what common ground then is possible with the IRGC? Did Saddam Hussein think it was a winning strategy to lecture the world about Kuwaitis pulling the strings in the original Desert Storm?

The IRGC and Iranian leadership assume that since Israel is just one nation, and not a big one, that they really really want to annihilate, it should be no big deal for everyone else to accept. But that is a dangerous, even existential proposal on both sides, as the IRGC knows, partly because the US position worldwide is about projecting security for partners.

Iran actually occupies a mirror position regarding the Palestinians, who have fought and suffered greatly. So Iran strives to reverse the positions of the Israelis and Palestinians— not to raise all ships, but swap them— which isn’t a moral cause from an impartial perspective, it’s just picking a different winner.

The US and Israel sought peace through negotiations for decades regarding the Palestinians, while Iran has continually plotted and waged war, which it now has on its home soil. The US and Israel have genuinely sought to peacefully resolve the situation, while Iran has not, not in my lifetime.

Israelis didn't "sought peace through negotiations for decades regarding the Palestinians". They have a long history if violence and apartheid policies, since the beginning. Negociation attempt have been done under the pressure of the US, and Israelis commonly break ceasefires, and favor the most extremist of their opponents to keep the tension going.

The problem with Israel is that the initial colonization was mostly illegal and problematic. Now, time has passed and countries should recognize its existence, while Israel should also stop its plans of a "greater Israel", including invading and bombing all of its neighbors. And stop the illegal colonization of the West Bank, along with their policies and ideology treating Palestinians like animals.

Israel is a rogue state, with illegal nuclear weapons, that protects criminals from all over the world and refuses to extrade them and commits war crimes in the open. Your way of thinking, which it is a pure white dove in a sea of evil muslims won't solve anything : Israelis have to do techouva if they want peace.

Unfortunately, the current far-right government pursues a religious messianic plan, including the destruction of muslim holy sites to rebuild the temple, so they won't accept a lasting peace.

Iran is however not an existential threat to Israel, as long as it doesn't have a nuke. So the efforts should concentrate on this aspect, to which the Iranians were open to discuss...until the Israelis assassinated the negotiation team and the supreme leader that could have imposed a desescalation deal.
