Dismantling Fake Nukes to Improve Global Security

I started reading this article at BBC thinking that the real issue was about actually dismantling nuclear weapons. I realized pretty quickly that the interesting issue was "how can a non-nuclear power monitor the dismantling, without aquiring nuclear technological expertise in the process?" If we really are going to move toward a nuclear-free world, this becomes an important issue, and I found the discussion of these mock excercises to be quite fascinating.
