Iran is going nuclear how?
The only nuclear explosion that Iran can produce now is a nuclear fart. We have 440 kilograms of 60% HEU in the form of UF6 that we can neither enrich it further, nor convert it into uranium metal. The US and Israel dominate our air space at the moment. Unless Iran has some secret underground nuclear facilities where we can further enrich our HEU and convert it into uranium metal, then an Iranian nuclear device in the near future is out of the question.
Yes, the late Khamenei said there would be no negotiations and no war. Just because Araghchi said that doesn't mean that it's going to happen.
Personally, I think Iran should not negotiate with the US at all, until the US accepts Iran's new terms. Iran at this point is the winner of this war. We should not sell short. But if the news about the negotiations is true, and you have been posting so much about it here, YOU not me, then Iran is selling short and we can all predict the outcome of that.
Iran hasn't lost the war yet. If Iran loses the war, Reza Pahlavi remains the first choice of Israel. Trump prefers somebody inside Iran because he's looking for a Venezuela-type situation, but if Iran gets defeated, then things will be very different.
Again, I don't think Iran has been defeated yet. We do have a fighting chance at this point, as long as we do not sell our position short.
