Ok how about this theory on what is happening.
US-stops oil shipments to N. korea
Iran-wants nuclear technology for a-bomb and has oil
N. Korea-has nuclear techology and needs oil.

Remember that ship with scud's that was caught just off the Yemen shore by the Spainish that was from N. Korea, it wasn't headed for iraq it was headed for Iran. My theory is North korea is giving technology to Iran for oil, and North Korea is using this time of confusion in the bush administration over it's decision on what to do about korea to build nukes

Some recent evidence showed that NK didn't get oil from Iraq, but from Iran. In the other hand, Iran purchased NKorean weapons. They just simply need each other. And to NK, to trade with Iran is much less dangerous than with Iraq, since US concentrated on Iraq a lot and made some millitary actions, which NK doesn't want at all.
