According to Washington Whispers:
A North Korean delegation is now secretly visiting Tehran for discussions with Iranian officials that are believed to focus on cooperation in the production of missiles or nuclear weapons, a knowledgable U.S. official tells U.S. News. The Bush administration has been watching North Korean-Iranian cooperation for some time, and North Korean scientists and technicians have previously been spotted at a town near the Caspian Sea. They are believed to be working on Iran’s development of longer-range missiles. Other officials also say the two countriesâ€“the remaining members of President Bush’s “axis of evil”â€“are working together on weapons of mass destruction.
We should nuke now and ask questions later.
