I majored in International Politics / Affairs in school. I took a National Security class where we spent weeks of the class discussing different types of WMDs in depth. It was terrifying beyond belief. One unfortunate consequence (if you can call it that) of the Cold War ending, is that people probably aren't as terrified by the concept of nuclear weapons / war as they were a decade or two back. People don't seem to care quite as much about the proliferation of these types of weapons, materials, etc. It's sort of a frightening concept to know they're all still there, there's extremely solid evidence that more than a few have been "lost" in former USSR countries, more countries are trying to make or acquire them, but people aren't nearly as familiar about the consequences or realities of the weapons themselves these days.
