well , you think how IRGC work when it take big project ?
do it all itself ? if you think so you cant be farther from the truth.
they take project then break it apart to smaller part and other companies do those smaller parts.
so when companies can't make money from bi project as they don't have enough money or experience
to bid for it ,IRGC make it possible for them to benefit from those projects.
well according to this map you can find some
but there is one different iran for last 30 years have difficulty accessing world markets and they had no such problems.
