The Storm of War is a non-fiction book authored by British historian and journalist Andrew Roberts. It covers numerous historical factors of the Second World War such as Adolf Hitler's rise to power and the organisation of Nazi Germany as well as numerous missteps made by the dictatorial regime. The inherent failures of the Axis powers helped in the massive efforts to force their defeat, which constitutes in Roberts' opinion, despite the massive bloodshed during the war, a moral triumph over authoritarianism by idealistic democracy. Praise has come from several publications; examples include The Daily Beast, The Economist, and The Observer.
