This doesn't really fit here at all, but I didn't feel that the bonfire or fluff zone were really that appropriate. Given Russia's recent posturing (that might be unfair; NATO has continued with flights since the Russians suspended theirs in the 1990's) this is vaguely topical/political.
I've just finished reading The Bomb: A Life (5 quid in hardback, a bargain) and have made my usual mistake of chasing up all of the references I can get hold of. Which is enormously time-consuming.
Anyway, one chapter made reference to a BBC 'docudrama' called Threads. I don't really expect anyone to watch it in full (and if you get your kicks out of Matrix-esque special effects, don't even bother trying), but it was probably the single most depressing piece of film I've ever watched. A synopsis can be found at Wikipedia (shock horror). In short, there's a conflict over Iran (heh) which leads to a full nuclear conflict. Britain (and presumably the rest of the world) suffers horrendous casualties, the effects of fall-out, the breakdown of social order, etc, etc.
"Great, but where's this going?" I hear you cry. Well, two hypothetical questions:
1) News reports indicate growing tensions between the US and Russia; ships have been sunk, troops have been deployed somewhere (let's stick with Threads - the conflict is brewing in the Middle East). The press is full of stories of escalating tensions. You've got a pretty strong feeling that nuclear weapons will be exchanged within the next two weeks. What do you do?
2) Ignoring (or perhaps taking into consideration, depending on your response) question (1) above, you've just received the 4-minute warning. What do you do?
Options are obviously numerous - do you build a shelter? Stock up on basic foodstuffs? Run to the hills? Seek death over life in a post-apocalyptic (I'm sure that's a contradiction in terms) world? Spend time with loved ones?
Obviously responses should consider the fact that (most) human beings are semi-rational actors and will pursue predictable paths; so if you plan to stock up on food, how do you plan to cope with millions of other people doing the same? If you plan to pursue a might-is-right approach, how would you go about it in light of the fact that there's always someone stronger?
Answers on a postcard please...
