What would have happened:Orion series commissioned,Soviets try to counter,Orion bombs Moscow, US nuclear superiority wipes out SFSR, NATO liberates Warsaw Pact.China last commie wanna be left.Sadly, I'm just vastly watering it down, its the jist of how things would have gone in the 1960s/70s.

Not really. The US would have effectively annihilated itself launching the Orion. (Add in the fact it's main weapons were also it's main fuel :p). The moment the Orion began launching the USSR would have launched to eliminate it, and would have succeeded, though the US would have launched in reaction to the Soviets launching in reaction to the US's original launching. 

We'd have had the whole nuclear exchange. End of the world Australians conquer the Earth :p
