In fact you just showed your own level of understanding...
Iran signed JCPOA that included Europeans and Russia... cheetos just tossed it out... it was working!
Tell me what guarantees Pakistan, Turkiye or Saudis can privide. They rightfully insisted on Americans because they could toss that out as the previous. Second, JCPOA allowed Iranian assets to be unfrozen in Europe and US. What kind of assets do Pakistan, Turkiye or Saudi possess that needed American permission to release?
Keep school yard remarks where they belong.
