And remember, if you are going to mess with history, look up the real version first.
Do not use soviet-stereotypes to project how they would act in your situations; look at the stability of the government, economy etc. at the point in history you stage something, and see if you can get the statistics to back up your alternate-history.
See if you can find any events that could turn out differently, like ones where simple human folly determined the outcome.
I cannot wait to see how this story turns out; it seems like a very interesting idea.
An arrow can only be shot by pulling it backwards. So when life is dragging you back with difficulties, it means that life's going to launch you into something great, so just focus and keep aiming. — Unknown
