<<The Soviet union could not have been invaded with the Forces NATO ever had.>>
Of course not, because Stalin kept their guard up and maintained a credible deterrent.
Shure he did .
That is why the West never invaded Russia.
There was another reason too of course , the WEst didn't want Russia.
Napolion and Hitler might have wanted Russia but with the passing of Hitler there was very little of that sentament left.
Stalin whipped up fear for reason of power maintenience.
And when that deterrent was shown to be hollow by Mattias Rust the emporors clothes became transparent.
I give Mattias Rust a lot of credit .
The People of Russia realised that they were killing themselves for an illusion of safety against aninvasion no one was prepareing , when the Soviet Union dissolved hundreds of ships were retired , Subs and missles , Americans were invited to help secure excess enriched Uranium. All over the place formerly secret locations were visited .
The guard was down , and just as Stalin predicted.... well no , just as in reality the USA never wanted to conquer Russia , we just didn't want to give up our freedom for the "benefits " of Communism. When they quit pushing on the wall the wall failed to fall on them , it just fell into the hanmds of souviner collectors.
