Equating the Soviet Union's role to that of Germany during the second world war is certainly uhhh.. one of the takes. It's not as if the US sent tons of food, aircraft, and hundreds of thousands of vehicles to the SU as part of lend-lease.
Pardon my French, but WTF are you talking about? Stalin took half of Europe.
It confounds me how people think WW2 ended with a success when millions were killed or enslaved as a result of the "victory".
In their mind it was the "price" to pay for relative stability in the west.
The status quo was sealed once Soviet Union has developed their own nuclear weapons using stolen IP. Had this not happened, most likely Stalin would have been pushed back.
