The International Security Studies Forum (ISSF) of H-Diplo is very pleased to provide a roundtable discussion of Dr. Jessica Weeks’s book, Dictators at War and Peace. The book offers an important answer to the centuries-old international relations question as to how the politics within states affect the politics between states? Since at least the Enlightenment, most observers have tackled this question by focusing on the differences between democracies and dictatorships, Immanuel Kant and others famously arguing that democracies are more peaceful. Realists have been skeptical of this claim, contending that all types of political systems conduct foreign policy similarly. Especially since the end of the Cold War, international-relations scholars have been consumed with the scientific exploration of the democratic peace proposition.
