Iran surely understands that key to its continued existence as a sovereign nation is dependent upon gaining nuclear weapons, just like other Chinese aligned economies, N.Korea and Russia. USA cannot sanction China which supports the economies and consequent military viability of Iran, Russia and N.Korea because USA is now dependent upon Chinese supply chains. USA might still depend upon Israel to attack Iran if a deal is not reached but such an attack could ultimately result in the destruction of Israel. Unable to end the war in Ukraine the USA cannot afford the Middle East to break out into a major war. The USA looks increasingly unable to project its will upon Chinas growing alliance of nations operating outside of its USD/SWIFT hegemony. China has won the trade war and its military proxies-economic subordinates are increasingly overwhelming US global hegemony.
