the Iranian official including the SL are living in 1980s and 1990s and don't dare to simply pull out of NPT and make nuclear deterance ...
We paid more than any country for nukes , but due some old guys in power and so many traitors, we are less likely to get nuke ....
in fact chance of KSA, UAE , Qatar and Turkey getting nukes are much higher than Iran ....
our top leadership is coward , they don't dare to change the situation and want to keep this status quo on spens of wasting Iranian lives ....
