Well, it is still an achievement if they built it from the ground up instead of kitbashing it from an F-5F.
Somehow, though, I think that is exactly what they did, in which case, big deal.
If they want to do something impressive, they should design and build a brand new jet airliner. It would be the first jet airliner every designed and built in the Moslem world.
Oh contraire! Lest you forget the Persians had jumbo Magic Carpet rides while us infidels were just crawling out of our caves.
The things the Iranians/muslims do better than anyone else is kill other muslims, talk big and ignore reality.
