What about the help the Chicoms got from the US on missile guidance systems? Do they have anything to do with making these missiles "marketable"? Wasn't it under Ron Brown's stewardship that the technology was given to the Chicoms by a leading US firm?
Yes...but that guidance, which came from Loral, was more geared towards intercontinental ballistic missiles (and therefore an even worse threat to the US). The guidance for these missiles is a different animal and an order of magnitude less complicated, albeit it is very complicated in its own right.
