Pakistan? See this report in today's Christian Science Monitor, which pulls together some earlier reports from both The New York Times and The Washington Post. It speculates that Pakistani scientists may have been the source of nuke technology for both Iran and North Korea. Combine this with Pakistani sources' known past, and possibly present, support for the U.S.'s Taliban enemy in Afghanistan, and the casus belli is there. It's a big, expensive, bloody world to subdue, and a rigorous application of Bush administration foreign policy wisdom could see the red, white, and blue mixing it up in 2004 from Persia to Peshawar to Pyongyang.
