What would have happened to the USSR if the Allies had lost World War 2?
Most likely, the USSR would have been overrun and the Communist
party would have been crushed, but nobody can tell for sure.
the real question is what would have happened to the allies if
the Russians lost the war. most likely, there would have been a
resistance until either the Germans fell back or Hitler died and
the Germans fell back. but again, no one knows for sure. alot more
people would have died.
