I think this is all the usual BS geared toward ripping Iranian citizens off by the international gang of economical terrorists on both sides.
an excuse to increase prices for the Iranian consumers, or increase inflation where the rich don't give a damn it only hurts the poor (and definitely wont hurt the damn regime).
I think sanction is a conspiracy to rip Iranians off, same thing they did in Iraq and elsewhere which also killed millions of children (ban food and meds)and didn't hurt sagdumb a bit!
btw I heard they have already banned most flights too , air france /klm don't go to iran! is that true?
