This realy is not that important. These leaders want nukes to protect and legitimize there standing in the world. Why would they risk sending a couple nukes at us when they know very well that if they did they would have 10 more coming at them. Mutually assured destruction still works.

Now what really scares the hell out of me is a terrorist buying a nuke from the Russian stock pile or from North Korea. Then put it in a container ship and set it off in New York Harbor. THATS SOMETING TO REALY WORRY ABOUT!!
