U.S., Japan seek N. Korea sanctions vote

This is highly contridictory for the U.S. Why are they even voting? U.S. is going to ignore the U.N. decision if it doesn't swing in their favor. To think that U.N. still has power is ridiculous, because U.S. made this entity futile when it went to war with Iraq with it's unilateral decision. Why not just go to war? If the Republican Party has a the Majority in both houses why don't they just declare war because its within their power to do so. Isn't it much easier to elimate enemies that you can see instead of searching for them? In my opinion, North Korea is not a top priority in the U.S. national interest or U.S. (Bush administration) is afraid to fight a real war.
