That's what India and Pakistan didIran has done a Hercules job while having decapitating sanctions on them ( somalia can't even function with no sanction on . )
they build their own weapons technology and they have reversed engineered the meds their people needed and much more....now imagine this sanction is lifted and the sky is the limit...I have this gut feeling that Iran has well thought out this and they thought to themselves " alright, sanctions are hurting us, we can make a decade old agreement with these people while we accumulating more knowledge, more industry, more farming hardware, more chemicals for our industry and when we reach that point where we reach a comfortable situation we can conceal our program once again and if we're caught we don't care"
