Yes, North Korea is different that Iraq. Whether containment will work is a question worth considering.
But that wasn't where I really wanted to go with this, based on your point above. The leftstream media will not care to see a difference - in fact Peter Lemmings is already foaming at the mouth because the Administration is not making bellicose ruminations about North Korea's actions. This is being done to drive a wedge with the American people by suggesting that if we are not willing to go to war NOW with Pyongyang, then we should not want to go to war NOW with Baghdad.
What the leftstream media once again is doing is believing that if it doesn't come from their mouths, the American people are too stupid to understand. By extension - they believe that if they utter something, the American people being stupid will believe what they say.
They are hoping for this because nothing else they have done in the last 13 months has worked one iota to lower the standing of President Bush.
Unfortunately from their perspective, the American people are smarter than they think; this won't work either.
