There was no will to go to war with the Soviet Union in 1945, none. We still had Japan to defeat and were far more interested in getting Stalin to help than to attack his forces (which were enormous, well equipped, and battle hardened). It was not a consideration by anyone who was serious. The US public was growing tired of war as it was.
Agreed and as one example of this:
My dad was born in 1940. One of his oldest memories was of a little parade in the neighborhood when the war ended. He (just turned five) and everyone in the neighborhood celebrated the war's end.
His parents bought him a bicycle as soon as they could after that. Like nearly all Americans at the time, they had plenty of money but there was nothing to buy. His dad (grandfather I never met) had worked his regular job (at the Electric Company) then a second job at a local aluminum casting plant that made aircraft parts throughout the war. With his two jobs they had good income but many items were rationed and many others were simply unavailable.
The newest bicycles were from 1942 before the factory switched over to war production.
The newest civilian automobiles were the VERY few 1942 models* built in 1941 and EARLY 1942 before the auto plants switched over to war production.
This was true across industries. Families like my grandparents wanted to buy bicycles for their kids, new cars, washing machines, etc, etc.
One of the considerations in dropping the Atomic Bomb was a concern among US leadership that the American people would think that Germany's surrender meant that the war was over and their support for continuing the war against Japan would wane.
*Among car collectors, 1942 models are very valuable because they are so rare. Very few were made and the few that were tended to get used up during the war since they were the newest cars available.
