Replacing American parts with good-enough parts from Europe, Japan, or Russia is the quickest way for Sukhoi to create a non-American version of Superjet 100 for export to Iran [COMPACTIDEA]

It won't be easy, but it's possible if there's enough will and enough action. Iran desperately needs these planes. Russia desperately wants to sell passenger aircraft - and Iran will buy hundreds if Russia can provide. US-made components stand in the way. Europe isn't a pussy that its companies cannot provide substitutes for American components. Japan and Russia itself can also be alternative providers [maybe Canada too]. Russia must seize this opportunity presented to its airplane manufacturers and supply the airliners Iran needs and wants.
