The Road to Iraq is an empirical investigation that explains the causes of the Iraq War, identifies its main agents, and demonstrates how the war was sold to decision makers and by decision makers to the public. It shows how a small but ideologically coherent and socially cohesive group of determined political agents used the contingency of 9/11 to outflank a sceptical foreign policy establishment, military brass and intelligence apparatus and provoked a war that has had disastrous consequences.
