No, you're still missing your own arguments, based on which this discussion thread has been based. Citing your exact words:

> Furthermore, if Iran declared that it did possess working nuclear weapons that wouldn't be a deterrent: it would trigger an immediate and massive preemptive attack by the USA and Israel.

I've been discussing this under the assumption from your own words that "it did possess working nuclear weapons" ('it' being Iran). If you are now changing this to a massive escalation before they even get it, then that is out of scope for this discussion. I would argue they are already doing that to the extent that they can, as they have to tread carefully since Iran can also destroy all key infrastructure in Israel as well.

A massive conventional attack against a nuclear power is historically not a thing. That's the whole point of a nuclear deterrent. No one is attacking Russia or North Korea under pretenses of humanitarian interventions. A massive conventional attack that would tear Iran apart would be a sufficient reason to initiate nuclear armageddon between Israel and Iran, as it would be a doomsday event for Iran either way; might as well go down swinging. Again, that's the whole point of a nuclear deterrent. It's what Israel's Samson option is, even though none of their enemies ever possessed nuclear weapons.

No ethnic cleansing will be required, and the dissolution of apartheid South Africa tells us how things will play out. Once the state is degraded enough, they will largely all emigrate on their own since the jewish supremacy that is currently in full swing will be no longer. They will not want to live in a state where others have equal rights. The few who don't mind it will remain and live on with the majority that currently enjoys little to no rights.

The point was addressed in the first sentence of my previous reply.

As for a preemptive attack, which I imagine you meant would be nuclear since they're already giving it all they've got with their non-nuclear attacks, it is already clear that Israel and USA don't have a way to stop Iran's faster missiles, and they would have no way to prevent Iran nuking Tel-Aviv and Haifa in return. At that point Israel would cease to exist as a state and as a society. They would never risk that. The entire decades-long war against the middle east by USA and Israel is fought for the benefit of Israel, not for its destruction.

There is no reason to believe that they haven't already developed and worked out the details of all that, in case they'd ever need it. Now the US and Israel have killed the only man who was preventing it from being done, the late supreme leader. I cannot imagine the next supreme leader (that is about to be announced) not immediately cancelling the prohibition on building nuclear weapons (to be made public only after they've been built, ofc), and giving the order to build ~10 nuclear warheads (the amount that they can build based on the amount of 60% enriched fissile material they currently possess). With two nuclear powers relentlessly attacking them, it would be suicidal of them to not order the immediate building of nuclear weapons ASAP.
