Book excerpt: In 1940 the world was on a knife-edge. The hurricane of events that marked the opening of the Second World War meant that anything could happen. For the aggressors there was no limit to their ambitions; for their victims a new Dark Age beckoned. Over the next few months their fates would be determined. In Fateful Choices Ian Kershaw re-creates the ten critical decisions taken between May 1940, when Britain chose not to surrender, and December 1941, when Hitler decided to destroy Europe’s Jews, showing how these choices would recast the entire course of history.
