It wouldn't have been just Germany vs the Soviet Union if the US and UK were not involved, Japan and the SU had reached a stalemate in their war, Germany kept pressuring Japan to attack the SU from the west, it wasn't until the Soviets learned Japan had no intention of attacking that they were able to move at least a million troops to the Eastern Front. If Japan wasn't occupied with the US and UK in the Pacific they would have pursued their fight with the SU trying up millions of Soviet troops and material.There were highly questionable actions taken by all sides - the British decision to bomb populations to provoke Hitler to do the same, and take the heat off its airfields; the US bombings of Hiroshima and Nagasaki, done more to make an impression on the Russians than to end the war quickly (the sticking point with the "unconditional surrender" of Japan had been the retention of the Emperor, and after the second nuke had been dropped the US allowed the Emperor to remain in place anyway)
Russia has to be thanked for resisting the single largest land invasion in the history of the human race, and for losing more people in doing so than any nation in history. So, I think that the victory should be given to them.
NOt sure why you think there were secret reasons to use the Bomb. It was Total War.
Russia? YOu mean the nation that started the war with Nazi Germany with the joint invasion of Poland?
Losing lives is generally not considered a measure of military effectiveness.
More than 80% loss of the German troops fell on the Eastern Front. Eight out of every ten German troops killed in World War II perished while fighting the Soviets.
Sure, the Eastern Front was a meatgrinder.
Imagine if Germany had thousands of more planes and tanks to use on that front, imagine if the German factories were not reduced to rubble, imagine if the thousands of guns used for AA were used to kill Russians, imagine if the Russians ran out of fuel, trains, trucks and food.
Or had to divert manpower to do those critical functions.
