The Battle of Kursk

LiannaSilverwind: Therefore you do not consider tearing apart (autumn 1938) and later occupying (spring 1939) remnants of independent state being act of aggression? What about its citizens who became second-class labour force for the Reich? How did they like the idea to either become Germanized or eliminated later?
By the way it is very interesting to read "alliance plans against Germany" between Great Britain, France, Poland and Soviet Union in summer 1939. You can check Richard Overy's "Russia's War" to check the ideas, feelings, proposals and intentions of all sides. Notice that one ally - Czechoslovakia - was already sacrificed in Munich.
