Is there any source to back it up ? or purely your opinions?
It's hard to believe that the US would need doing that (AESA and carbon composite)
I believe you can read it at wiki or dig something up with a google search.
It was also at the height of US export deficit in which Japanese cars were forcing the Big 3 into the corner while Japan stood on with minimum access to import of rice and beef.
Mr. Morita of Sony wrote a book titled "Japan as No.1" didn't really do much good either. LoL
In any case the vast R&D was the main reason for the F-2 being such an expensive plane even though it's based on an already mass produced airframe.
