> Iran can't have a nuclear weapon. It's an intolerable premise and if the price to be paid is global oil catastrophe it's a price well worth paying
Says you.
All other nuclear nations behave (even Pakistan and India, which are at each other throat all the time). What makes you think that Iran won't? It will also have Russia and China keep a lid on them, same as North Korea. And I don't buy the "Iran is different" gospel. North Korea and China have completely different mindsets than the western world and still play ball.
Additionally, if Iran really is that adamant in getting nukes, I can see them asking some enriched material to Russia as a payment to the 100s if not 1000s of drones they are giving them. They share a "land" border through the Caspian sea and smuggling a few 10s of kilos of enriched material would be relatively easy.
Finally, it is not a good proposition if the hypotethical benefits will be reaped by US/Israel while the suffering is globally spread.
