You see, the USSR at Andropov's time had much better strategy without the high precision stuff. Conquer the continent and don't let the US to help it. Then, eventually the US would not be able to sustain NATO alone when the world market will shrink. So, the communists in the US would eventually win. Problem solved. (Of course, relatively young Andropov did not live long.) It won't be clean like that in case the NATO would assault Russia. Not sure if the 10-15 million is a price the US politicians would be willing to pay.
