Do yourself a favor, and read this exceptional article from The Atlantic Online. If you subscribe to the Atlantic Online, you can also read the second half of the story, which is even more incredible. Maybe I just get excited about this because nuclear nonproliferation is my business, but this is some of the most eye-opening stuff I have ever read. Unfortunately the part that I think is most important to the genereal American audience is in the second half. It discusses what our intelligence apparatus knew about Pakistan's involvement in nuclear proliferation to North Korea, Iran, and Libya, and as a result brings up some serious questions about the nature of our strategic partnership with the Pakistani government in our fight against "terror." I think this article alone is so worth reading that it justifies the expense of a subscription to the magazine.
