It's a commonly held belief that Adolph Hitler and his Nazi regime were intent on war mongering and world domination. But in this documentary, historians argue that diplomatic efforts and certain alliances may have changed the course of world history and prevented the Second World War. A basic misunderstanding of Hitler's aims and political desires led to a conflict that could have been avoided.

Even after the Second World War began, there were attempts to appease Hitler to avoid further conflict. In this documentary, historians reveal that British political and public opinion, as in the rest of the country's European allies, were hesitant to stand up to Hitler’s Germany. But this hesitancy led to an even more brutal conflict and wider Nazi atrocities.
