if that's true then dropping the bomb to send russia a necessary messsage as JH and TR asserted would be false.
Well, we didn't know they knew. The US and UK had not been sharing any information with the USSR on the development of nuclear weapons and when Truman mentioned it "in passing" to Stalin at Potsdam he reacted with so little interest that Churchill and Truman figured he just didn't understand the importance of what they told him (in reality, he was deadpanning and hiding the fact they had completely penetrated the Manhattan Project).
From Marshall Zhukov's memoirs:
“Churchill and many other Anglo-American authors subsequently assumed that Stalin had really failed to fathom the significance of what he had heard. In actual fact, on returning to his quarters after this meeting, Stalin, in my presence, told Molotov about his conversation with Truman. The latter reacted almost immediately, ‘Let them. We'll have to talk it over with Kurchatov and get him to speed things up.’"
Kurchatov was the head of the Soviet nuclear program, their version of Oppenheimer basically. He was receiving pretty much daily updates on the progress of the Manhattan project as early as 1941 - so detailed that the first USSR weapon RDS-1 was nearly an exact copy of "Fat Man", which was the bomb we dropped on Nagasaki.
That being said, with the USA/UK unaware that the USSR was that well informed of our nuclear programs, there might have existed some sentiment to demonstrate the power of the weapons to discourage any expansionist activity in Europe or Asia in the post war period, but there's little evidence of that from the time. The Soviets certainly were not making post-war decisions any different because of Hiroshima and Nagasaki since they were already fully aware of the weapons and their capabilities.
FWIW - the benefit of being married to someone like vadtoy who has such a deep insight into a specific field is I get to do things like sit at Kurchatov's desk in eastern Kazakhstan and flip through his hand written journals (including basically exact copies of the plans of the US weapons) and visit ground zero of the Soviet's first bomb. When I say vadtoy is an expert in the weapons and nuclear policy of the former Soviet Union, I mean literally one of a very handful of people in the world who know it in as much depth as she does.
