Not so minor, in the sense of commies having a nuclear capability before we did.
Imagine the total lack of handwringing, reflection, or regret from an Atomic Stalin using his weapons.
If Stalin had the bomb in '45 instead of the USA, then at the very least we would have seen half or all of Japan occupied by the Red Army and probably more of Europe such as Austria and Denmark.
We would not have been completed impotent facing a few atomic weapons but it would have changed things.
Only as a matter of convenience and "enemy of my enemy". If Stalin had the bomb at the end of WW-II, and we didn't', WW-III would have commenced very shortly thereafter. The world would have been a very different place than it is today.
