I have thought for a while that NK's missile test was designed to impress Iran rather than frighten civilized nations.
Iran, flush with cash, appears to need a delivery system for their weapons. NK, among the world's poorest nations, would have no problem selling this technology.
Thats the scary part. Would North Korea would sell this teachnology. The answer is probably yes.
It was said on Fox News TV Channel this afternoon that Iran is actually funding the North Korean development of the Taepodong missile.
It's probable that Iran will be the first Taepodong buyer if North Korea succeeds. Iran threatens to use the Taepodong to nuke Israel.
