Greetings from Ukraine, country at war with Russians, who thought they are genuine descendants of USSR.
Long before Ukrainian war, I've many times talked with Russians about bombs used on Japan.
And now I must say you very important thing - Russians are so crazy anti-humanists, that this really could be reason for fears of Japanese about USSR invasion.
To be honest, I think bombs was enough to intimidate Japanese, but I think, even without bombs, Russians behavior at war, with US Land-lease technical/economical support would be enough to convince Japanese to surrender, may be later, sought.
