A great deal of factual information can easily be found concerning the involvement of all countries in World War II, such as information found in the article "World War II by Nation."
One interesting fact is that in the 1930s Great Britain actually enacted the policy of appeasement in order to try and avoid a second world by "appeas[ing] Germany" ("World War II in Britain"). To that end, the Munich Pact was signed in 1938, allowing Hitler to attempt to recapture Sudetenland in Czechoslovakia, land that used to be inhabited by Germans under the Austrian empire (BBC, "Hitler's Plans for Czechoslovakia").
