I think the world champion in disregarding UN resolutions is Israel, not the Iraq. That's only by the way.
I have the strong feeling that the U.S. was tricked into this war. According to coverage of German TV news a spy from Israel in the Pentagon fed the brass there with wrong informations as to alleged WMD in Iraq.
As a matter of fact the only ones who took advantage of this war were the big companies and.... Israel. Now the U.S. do the dirty work for them. It was also reported in German newspapers that doctors, engineers and university lecturers in Iraq are murdered systematically in order to destroy the elite in Iraq.
Suspects are the Iran and Israel.
Back to Korea: The Koreans have no reason to shoot at U.S. planes because U.S. planes don't violate their territory like they systematic used to do in Iraq (based on a UN resolution, though).
No one with a sound mind can claim that the world is a more safer place now. On the contrary: The price for crude oil is rising tremendously, so is the number of terrorists and terrorist attacks. The wildfire of terrorism is spreading even more now.
This war was fighting a fire with gas. I think, Saddam was the minor evil. With the war on Iraq Pandorras box had been opened.
Those who don't believe it will learn it (the hard way) during the following years.
