Why Was D-Day So Significant for Poland ? [266]
Would Stalin have been able to finish Hitler without D-Day
In my estimate, yes they would have been able to do that alone. At the stage of the war the outcome was pretty much decided, it was only a question of time.
One could speculate what would have happened IF the west wouldn't send munitions' and supplies to Soviets in 1942. or what would have had happened if Germans wouldn't have to fight British Empire and USA on the seas, in Africa and so forth.
There is not denying that Soviets managed to survive for two years of the onslaught and in 1943 got a breakthrough. One only need calculate and gauge how much of the help supplies and munitions' actually were in the overall Soviet effort.
It is a difficult one to answer. All - what if questions - are like that!
I have no enough data for that to hazard a guess.
