Russian army was several thousand miles away. Would have been months before they could have had any effect.
Stupid, perverse old liberal talking point.
Soviet forces already in the Far East were poised to invade Manchuria and capture and disarm Japanese soldiers.
Two days after Hiroshima was bombed, and it was clear to even a blind man that Japan could be A-bombed to smithereens, the Soviets finally declared war on Japan.
They then promptly invaded Manchuria and captured millions of Japanese soldiers.
As a consequence of two days of fighting, the Soviets were rewarded with the southern half of Sakhalin and the Kurile Islands.
