Historians and political scientists alike should appreciate Dan Reiter’s How Wars End. It eschews statistical analysis for comparative case-studies because the answers are “complex and nuanced” (6) and defers formal proofs for plain-language explanations. The six empirical chapters are based on case-specific puzzles rather than theory-driven questions. The three reviewers—Dale Copeland, Hein Goemans, and Zachary Shirkey—find few major flaws with How Wars End, although each has some reservations over aspects of the argument. Because some readers might not be versed in rationalist theories on war that Reiter engages, this introduction will first provide an overview of them and then discuss the reviews in the next section.
Dominic Tierney’s How We Fight: Crusades, Quagmires, and the American Ways of War is an unusual achievement. It is a provocative scholarly book about the U.S. approach to war that was written for a broad non-academic audience. For the academic and layperson alike, it succeeds in establishing that the heated controversies of the moment follow a familiar pattern. Indeed, it is impossible to read Tierney’s book without reflecting upon recent events. The Obama administration has struggled mightily to define (and redefine) the U.S. mission in Afghanistan; it has announced deep defense cuts though the United States remains at war; and with the shift in defense budgetary priorities, it will trim the very capabilities (for counterinsurgency) that U.S. leaders had once viewed as keys to success in Iraq and Afghanistan. But what led the administration finally to act? Was the administration recognizing belatedly that the public would not tolerate nation-building efforts? Or had the clock simply run out on the U.S. effort?
In the following exchange Dan Reiter defends his argument that democratic states win most of the wars that they fight primarily because they choose which wars to engage in more carefully than authoritarian states do. This is called the “selection effects” explanation because democracies are selecting which wars to fight and which to avoid. Here, Reiter is replying to previously published criticism by Michael C. Desch and Alexander Downes that detailed examinations of several historical cases that Reiter cites do not in fact support his arguments. Desch and Downes respond and then Reiter has a rebuttal. They primarily debate both how historical evidence should be interpreted and how their hypotheses should be evaluated in the 1920 Russo-Polish War, the 1956 Sinai War, the 1967 Six Day War, the 1982 Lebanon War, and the 1965 escalation of the Vietnam War.
Are democracies more likely to win the wars they fight? This question has been of interest to historians and philosophers since Thucydides. During the Enlightenment, the question was highly relevant to the great issues of the day, as thinkers such as Thomas Paine wondered how emerging republics like the United States and France would fare in war against monarchies. It reemerged in the twentieth century, when some worried whether the Western democracies had the stuff to stand up to Nazi Germany and its fascist allies. After World War II, Westerners fretted that an American Athens would ultimately fall short against a Soviet Sparta.
