Totally wrong.
With the use of tanks, the Soviets had previously beaten the Japanese in the Soviet Japanese border war of 1939, and they surrendered peacefully.
In fact, the Japanese clearly WERE trying desperately to surrender to the US for over a years, since we mined the China sea and were starving the civilians to death.

Japanese records report 8,440 killed, 8,766 wounded, 162 aircraft lost in combat, and 42 tanks lost (of which 29 were later repaired and redeployed). Roughly 3,000 Manchu and Japanese troops were taken prisoner during the battles. Due to a military doctrine that prohibited surrender, the Japanese listed most of these men as killed in action, for the benefit of their families.
[58] Some sources put the Japanese casualties at 45,000 or more killed, with Soviet casualties of at least 17,000.
[31] However, these estimates for Japanese casualties are considered inaccurate as they exceed the total strength of the Japanese forces involved in the battle (estimated at 28,000–40,000 troops, despite Soviet claims that they were facing 75,000).
[59][10] According to the records of the Bureau 6A hospital, the Japanese casualties amounted to 7,696 killed, 8,647 wounded, 1,021 missing, and 2,350 sick, for a total of 19,714 personnel losses, including 2,895 Manchu casualties. The Kwantung Army headquarters and their records give a slightly different figure of 8,629 killed and 9,087 injured. The former Japanese Minister of agriculture and forestry estimated a total of 35,000 to 36,000 casualties
[10] The Soviets initially claimed to have inflicted 29,085 casualties on the Japanese, but later increased this to 61,000 for the official histories.
