To my surprise, this question I asked was closed as "primarily opinion based", when I asked for evidence of Soviet strategy. I has assumed, perhaps naively, that it would be obvious that an answer would require references to official documentation from the era.
So I don't know how that would be opinion based. Whether the USSR in the aftermath of the second world war was keen or able to invade western Europe would surely have been written down somewhere, and further that we would see evidence of plans changing before and after Soviet leadership became aware of the existence and threat of American nuclear weapons.
How could I have better phrased the question? Is it just that it was too ambiguous, and I needed to lay out the need for policy to be referenced to support an answer? Documents which supported/countered that their leadership concluded they were:
1 Able to invade 2 Willing to invade and 3 Threatened by American nuclear weapons
