I bet the people on the left coast and in Hawaii disagree with you.
This is an unpopular sentiment around here, but I worry more about NK than I do Iraq. We can contain Iraq quite easily. Hell, the only country that probably feels directly threatened by Iraq at this point is Israel, and if Iraq wants to play with WMDs, Israel will melt Baghdad to the ground, and Hussein knows it and that does keep him in check (Hussein is more evil than crazy - he's crazy no doubt about it, but he's sane enough to want to keep control of his country). I would even through in the spiel about the Saudis killing many times more Americans on 9/11 than the Iraqies have in the past 12 years.
North Korea on the other hand - Kim is just plain ****ing crazy. He is working his butt off (or rather the butts of his engineers and scientists) so that he can hit the US from where he is at, and he is bragging quite openly about it (nevermind that we are feeding half his country). We are sitting here playing with Iraq, and if we don't do something soon about North Korea, folks on out west are going to have to start thinking about bomb shelters again.
We don't have a "shield" to protect us from NK's missiles in a year or two, and while they aren't sophisticated guidance wise, when your playing with nukes, you don't have to be that accurate. Germany did a damn good job of hitting London with conventionals and doing a lot of damage and causing a lot of chaos, with 1930s and 40s technology.
