Maybe- just maybe- if Hitler, instead of allying himself with Stalin in 1939, had
attacked it THEN, instead of in 1941. There
we're many in the UK- especially in the circles of the then-governing Conservative
party- who so despised Communism that they would have been happy to range the
country on the side of another nation actually fighting the reds(& IOTL, hatred of
Russia in these circles was so strong that
when it attacked Finland in November 1939
these people mounted a campaign to "switch
the war" from Hitler to Russia: "We'll all be
marching against the Russians in the Spring"
a British army officer actually predicted.*)
