From World War II to the war in Iraq, periods of international conflict seem like unique moments in U.S. political history—but when it comes to public opinion, they are not. To make this groundbreaking revelation, In Time of War explodes conventional wisdom about American reactions to World War II, as well as the more recent conflicts in Korea, Vietnam, the Gulf, Afghanistan, and Iraq. Adam Berinsky argues that public response to these crises has been shaped less by their defining characteristics—such as what they cost in lives and resources—than by the same political interests and group affiliations that influence our ideas about domestic issues.
