Yes!............
By allowing the Russians to get to Berlin first, they had a head start in divvying up Europe.
Also they had snatched some rocket scientists that allowed them to get their space program going................
The allies didn’t “allow” - let’s be blunt, there was little they could do. The Italian campaign had hit a stalemate and it took until 1944 for D-day, while the Russians were already hammering in Poland.
There was no way to prevent the Russians getting to Berlin first.
And it cost them about the same number of troops we lost in the entire French campaign. No thanks.
“By allowing the Russians to get to Berlin first, they had a head start in divvying up Europe.”
For starters that agreement had been made at Yalta in February.
The Pacific war was still raging. The first test of the atomic bomb was months away and we had no idea if it would actually work. A conventional invasion of Japan would result in an estimated one million casualties and we didn’t want all of them to be American. We wanted Russia to share in the carnage. So you don’t alienate them over Berlin.
