It seems that U.S. and Iran do not want to meet in person until Major differences have been bridged. I think that is why we are seeing Pakistan going between US and Iran.
There is also the matter of security for Iranian delegation every time they travel. So in Iran’s eyes the next time they go to Pakistan there should already be a framework agreed to.
To me, Trump is owned by Bibi and the Zionists. If the war ends, Bibi’s corruption trial starts. Thus it’s in his interest for this war to continue. So these negotiations are either Bibi’s surrender terms or just a cover to prepare for a larger war.
Why would U.S. be asking random companies to turn their factories into World War arms production facilities?
I am very pessimistic on U.S. intentions. Smells like a trap.
