Guess I am too, because I haven't heard an explanation as to why we have to invade Iraq, when we DON'T have to invade N Korea -- even though it's N Korea that's explicitly, loudly threatening to build a nuclear weapon and to launch it at S Korea or Japan -- or us.
Maybe the evangelicals on freerepublic would care about this if there were something in the book of Revelations about N Korea, but as it is, they're more interested in some kind of prophecy about the Middle East than in responding to real threats to US security.
