Look at the US Army in Europe during WW II..We accomplished amazing military victories. Yet the overwhelming number of American WW II histories, either ignore, or give lip service to the fact that the Russians chewed up over 50% of German military strength BEFORE we entered the war, and even after we entered..Africa, Italy, then France, the vast majority of German forces were committed to the east. The average America knows well the great battles of Western Europe, yet has NO idea of the monumental scale of the conflict in eastern Europe..FRance pales by comparison.
The US victory over the Germans was primarily one of logistics. We had more troops, more weapons, and a far better supply system.
Basil Liddell-Hart, viewed by many as perhaps the finest military analyst/historian of he 20th century, has written, in his History of WW II, that every time US and German forces facing each other were somewhat equally matched in troop strength and weapons, beginning with Kasserine Pass, the Germans won.
This is not to suggest that one wants a "fair fight" in war. Just the opposite.
So while the author of the article spouts the usual liberal tripe about the inhumanity of nuclear weapons, I suspect that there is a solid element of truth in the underlying thesis. The Japanese always had the majority of their forces in Manchuria..
