We had nukes.
Yep, we had three as of July, 1945, used one as a test and two on Japan, and enough fissile material to make seven more by end-October. After those it would have taken months to process enough material to build more bombs. One would have to expect, considering how deeply the Soviets had penetrated the Manhattan Project, that they knew this and once Japan surrendered they weren’t about to risk losing Moscow and six other cities.
“We had nukes”
Yes we did. All past tense. We used the 2 workable bombs over Japan. There wasn’t a nuclear arsenal at that point in time.
The war was over. Our troops were tired and the Soviets would have home field advantage. Of course they were tired to BUT, we didn’t have commisars with machine guns ready to mow us down if we retreated. We didn’t have battalions of political prisoners to march through minefields clearing them for troops and tanks.
I think it would failed. The Germans were toast at this point in time as well.
