The War Game, by Peter Watkins - not to be confused with War Games, starring Matthew Broderick.
Just watched this. I'd forgotten how we used to be obsessed that we would imminently be wiped out by a Russian nuke.http://en.m.wikipedia.org/wiki/The_War_Game
These days of course, we're obsessed we're imminently to be wiped out by a Muslim wearing exploding under garments.
Hmm, I'm detecting a pattern. Maybe the authorities just like us to keep obsessing about horrible things.
