Depending on how isolated they become. I think it is possible they become more like Iran. And energy rich state that is poor and run by fanatics.
Then you're falling into exactly the trap that I outlined.
I did not intend to get into a "SU-35 vs F-22" debate.
I'll say that I absolutely believe the F-22 is superior. The F-35 - frankly that does not yet exist in service (and neither does the PAK-FA).
But none of that really matters.
What I'm saying is that the fact that an SU-27, SU-30, SU-35
exists in the first place and that they originate from Russia implies something.
Specifically, that they are not like Iraq, Iran, Egypt, Libya, Syria - who all make nothing.
The fact that Russia designed, tested, built, and exported those weapons implies a magnitude of order more capability on their part.
And you're comparing the country that built and designed those aircraft to Iran, who builds exactly what? Oh wait, they've spent the last 10 years trying to make a nuclear reactor - something Russia did what, 65 years ago?
