Iran-US meeting in Oman tomorrow. Iranian foreign minister and Witkoff.
I think they have five main topics: nuclear weapons, nuclear energy, missiles, regional stability (ethnic minorities, political opposition groups, often with cross-border relations), sanctions.
Will the US arrive with ultimatum or do they really negotiate?
Netanyahu and co. are still shitting themselves so I assume they are putting equal pressure on Washington to what they feel.
The missiles are still a card in the hand of Iran. If they give up the weapons they'll end up like Libya.
I don't think anyone wants Iran having nukes, but that's the only (realistic) path that can give em some kind of peace. On the other hand this could trigger others to get on their hands on some.
China said recently Iran has the right to have nuclear energy production.

If Iran collapsed some rogue groups could get their hands on some nuclear material for couple of dirty bombs. I doubt this is in anyone's interest, no in US' or Israel's. Or maybe it is, great for scaremongering and more "anti-terrorist" surveillance.
