If US attacks N. Korea then it eliminates the N. Korean threat in the region.
This would bring Asia one step closer to unifying as a block similar to the EU, and the US losing influence and dominance. As long as things remain unstable, Asian countries remain in the US sphere of influence.
American foreign policy isn't that difficult to understand.
The difference was Iraq has oil... the US dollar is backed by oil since going off the gold standard. Untill recently you virtually couldn't buy oil anywhere in the world unless you paid in US dollars. Now some countries are starting to accept payments in Euros. This is a major shift in the world econonmy and especially for the US.
Iraq had begun to sign deals with many european and russian companies to drill and sell oil in Euros. It was shortly after that the war began and guess what... Iraqi oil is now only sold in US dollars. The US is scrambling to maintain control over it's currency... the oil is not for the US and will not be burned in the US.. .it's purely economic. Funny how the mass media doesn't disseminate this info... but sometimes you can find it in the back of the business press.
