Foreign policy makers and international relations scholars have become increasingly interested in the relationship between democracy and war. In this book, the author argues that the international relations of democratic states are best understood in the context of the interaction of democratic and international politics. Elections are an essential institution of democratic states, while war is a defining element of international politics. This book examines the interaction of these two elemental phenomena.

All state leaders must deal simultaneously with internal and external pressures. The conjunction of domestic electoral pressures and international pressures for war presents an acute form of this dilemma. Those who support increasing democratic influence on foreign policy have argued that this influence would make states more peaceful, while others have asserted that it would make foreign policy more volatile.

The author shows that democratic publics have been vulnerable to excessive enthusiasm for war, but that this enthusiasm is tempered in an electoral environment by the ability of politically legitimate antiwar leaders to increase the domestic costs of going to war. Democratic leaders may have an electoral incentive to seek out international conflict, but they also have a strong motivation not to allow such conflicts to escalate to war when elections are imminent.

The author also argues that the transparency of electoral politics in a democracy can lead to changes in the behavior of other states. Electoral institutions serve as an effective commitment mechanism for democratic states, and other states want to avoid contributing to the favorable electoral prospects of hawkish candidates. The author supports his argument with both structured case studies and analysis of the aggregate experience of all the democratic states over the past two centuries. He shows that despite variation in public attitudes toward international conflict, democratic states have engaged in significantly fewer wars in the period leading up to elections than in other parts of their electoral cycles.
