Broken Arrows, or "Whoops, I Nuked It Again" (Fallout Fans, Take Note)
If you've run an espionage game, chances are, at some point, a Big Bad has gotten hold of a nuclear weapon to threaten world peace/stability/financial structures/other important institutions. Even in this day and age, and maybe even because of the events of the day, nuclear destruction has returned to the popular consciousness, our parents' boogieman given new legs as "the dirty bomb" and fissile material." But take note, conspiracy theorists - there's reason to be nervous.
As it turns out, we've dropped nukes accidentally all over the US and the sea, particularly in the footloose and fancy-free years of the 50's and 60's. It seems popular wisdom of today' s leaders rings true; most of the time, the U.S. nuclear arsenal was a greater threat to the U.S. and its interests than it was to its enemies. While this comes to no surprise to those of us raised in the post-MAD era of perestroika and a collapsed Soviet Blok, the number of nukes which have been lost is really quite serious.
Makes me think a serial involving a out-of-work union worker who uses something special he recovered when deep sea fishing to get back at his bosses, or a jilted teenager who stumbles across a lost nuke in a North Carolina gully and uses it to threaten a Columbine-styled disaster, would make a very interesting 'shades of grey' Spycraft scenario...
