The biggest challenge the next president faces almost certainly will be an unexpected disaster, says Tevi Troy, author of Shall We Wake the President? Two Centuries of Disaster Management from the Oval Office.

In a 10-minute conversation with The Bookmonger, Troy talks about disasters in all their forms, from terrorist attacks to the Zika virus, and describes the role of presidents, the federal government, and ordinary citizens in prevention and response. He points to the worst disaster-manager in U.S. history (we're looking at you, Woodrow Wilson) and predicts the event that will come to be seen as the great disaster of the next four to eight years.
