That doesn't even consider the sheer costs involved. If Iran was a more open country it's government would cancel anything like that. It is simply unaffordable. I suspect Iran's aerospace industry keeps itself going either by pretending it has the capability to compete with the big powers or simply that it goes along with with madder fantasies of it's theocratic government who clearly have no idea of the real complexities involved.
I think the Iranian aerospace industry goes along with the madder fantasies of mullah's in charge. The video of their 'stealth' fighter wasn't really intended for western audiences but rather internal to show the common Iranian citizen that their country's technology and military industry is on par, if not, superior to that of the West. We of course know this is just an Iranian fantasy but to the average Iranian, to them it's true.
