the scenario you talking about is NOT exist,This is why we have a nuclear program and are continuing to develop more advanced centrifuges. We need to reduce our breakout time as much as possible. Should the USA or Israel resort to nuclear weapons to disable these bases, the designs and centrifuges need to be in place to rapidly enrich to 90% and assemble a few warheads within 1 weeks time in smaller facilities.
let say: the U.S attacks with Low-Yield nukes and we survive that, you think after 15 minutes that U.S satellite go over the impact point and realized that we have survive first strike they just going to leave it and walk way ??
let say they do walk way , and we start enriching to 90% and after week we have enough fissile material for Uranium bomb and start assambaling a warhead and after a month we have one or two or three warhead . the plutonium depending on type or even Thermo will be totally different timeline
let assume for argument's sake that, meaning we have to wait one half month and then after conflict is over we are going to strike back, really after everything is over and casualties are counted and public are wear we just going to star all over again.
let say we do strike back after we enriching to 90% assembled 3 warhead,
then again we run out of nuclear warhead and out stock reaches Zero and you think this time U.S will not retaliate heavely using deployed warhead ? and you think we ging to survive the second U.S strike ?? and you think that again the U.S going to give us one and half month to go make more nukes ?
this is why i made my first post specially for Iranian members so they come out of delusions and fantasy and start recognizing reality, with all of this simple info i just provided and my knowledge, I was talking about the reality of our capability and posture
