| The Big Question in this gallery focuses
on the relationship between the wartime allies Britain, the USA and the
USSR. As you look at this area, it is worth remembering that in 1939-40
Stalin appeared to be just as much a villain as Hitler.
But in June 1941 everything changed. Hitler turned on Stalin and invaded the USSR. The decisive conflict of World War 2 began, which Stalin won, but at a terrible cost. The sources in this area look at how the allies worked together, and how the allies wanted their own people to see this co-operation.
