Well, as long as we're on the subject of alternative histories...
I'm presuming that everyone's seen this site?
The Alternative History Wiki
The place is jam-packed with stubs and 1/2 formed ideas and very little of it is well-developed... except this
Doomsday: 1983
Here's the setup:
Col. Stanislav Petrov is NOT the officer on duty at the Serpukhov-15 bunker near Moscow. A different officer on duty at the bunker misreads a computer glitch as an American attack, sparking global nuclear war between NATO, the Warsaw Pact, and China. This timeline is the story of mankind's re-emergence from the aftermath.
Now, 25 years later, mankind is seemingly securing its survival. New coalitions and alliances have emerged from the ruins of near-total nuclear destruction and the League of Nations foundation is the first sign a better future for mankind. But a new threat is rising in the heart of the Old World once more.
So it isn't really TW2K, because what we seem interested in is the world as it's sliding downhill, about to begin pulling itself up, just a couple of years after the nuclear war. Doomsday 1983 takes place an entire generation after the war. However, check out the maps and the rather impressive collection of flags that have been created for the alt hist.
