This book is a very good political (not military) history of the war. It's based on U.S. archives, so it's told entirely from the perspective of U.S. policymakers, even when discussing French or Vietnamese events. Also, although the book is about as objective as possible, you really can't leave politics behind when you write about Vietnam. Schulzinger believes that the United States could not have won the war; that we got involved out of misguided good intentions rather than evil motives; and that the Vietminh and Vietcong were homegrown liberation movements, not puppets of the Soviets or Chinese. Those are common and reasonable views, so I'm just saying know what you're getting. Overall, I preferred Karnow's Vietnam to this book. Karnow's politics and focus (U.S. policymakers) is similar. Schulzinger, a historian, has better command of the written source materials, but Karnow, a journalist in Vietnam during the war, is a better writer and rounds out the story with his own observations. Still, with all those caveats, this is a very readable and informative book.
