Diplomacy
Diplomacy is the art of managing relations between states, and its failures can be catastrophic. Christopher Clark's The Sleepwalkers is a study of the diplomacy that led to the First World War: the alliances, misunderstandings and crises between 1903 and 1914, and how leaders who did not want a world war took the decisions that started one. A brilliant, detailed and gripping history. More books on diplomacy will join this category; see International Relations for more.
