Has anyone pondered an alternative timeline pre-1993? I mean, we all know that the Soviet onslaught is quite a stretch but what if...?
What if Stalin didnt kill off all the able officers and such? (one can argue that this more or less led to the dissolution of USSR)
What if Soviet attacked US during the 70s, during the great inflation?
What if Soviet managed to ally with Arab Oil States?
What if Warsaw Pact grew stronger, included say Italy, Greece and France?
What if US got stuck in Vietnam, and Soviet never invaded Afghanistan?
And so on. This would probably shift the power balance in favour of USSR. And suddenly the Soviet coup detat and invasion seems quite fair.
