At times, even his admirers seemed unsure of what to do with General Douglas MacArthur. Imperious, headstrong, and vain, MacArthur matched an undeniable military genius with a massive ego and a rebellious streak that often seemed to destine him for the dustbin of history. Yet despite his flaws, MacArthur is remembered as a brilliant commander whose combined-arms operation in the Pacific -- the first in the history of warfare -- secured America's triumph in World War II and changed the course of history.

In The Most Dangerous Man in America, celebrated historian Mark Perry examines how this paradox of a man overcame personal and professional challenges to lead his countrymen in their darkest hour. As Perry shows, Franklin Roosevelt and a handful of MacArthur's subordinates made this feat possible, taming MacArthur, making him useful, and finally making him victorious. A gripping, authoritative biography of the Pacific Theater's most celebrated and misunderstood commander, The Most Dangerous Man in America reveals the secrets of Douglas MacArthur's success -- and the incredible efforts of the men who made it possible.
