Chapter 23: The author's choice of the ten worst American generals
Chapter 24: The author's choice of the ten best American war films
Now all of that information is great. But the problem comes from the fact that about 250 years of military history is being crammed into one book. Chances are, if you paid attention in high school, you probably already know more about World War II than the information that this book has to offer. For lesser taught subjects, such as the Mexican-American War, the book does provide a decent introduction if you are completely unfamiliar with it.
The book could have been organized better in my opinion. The most curious thing is including a whole chapter on the Cold War. That chapter mostly just covers the political events that occurred. As a book about military history, I wished it would have covered U.S. military events more in-depth. The invasion of Grenada gets only two sentences. The invasion of the Dominican Republic is not mentioned at all. Both of these are two Cold War military events, albeit rather small and little-known.
Also absent from the book are some of the more minor conflicts the U.S. has gotten into over the years such as the series of interventions in Latin America, or the "Banana Wars" as they are sometimes called, of the early 20th century, the invasion of Panama in 1989, or the U.S. involvement in the Yugoslav wars. None of this is even mentioned in passing.
On the flip side, the book does a decent job of covering the major wars, namely ones most everyone has heard of, without getting into the nitty-gritty detail.
I enjoyed this book when I read it, despite some shortcomings. If you want a big picture description of the major wars the United States has been in, without the little details, buy this book. If you are someone who already knows a decent amount of U.S. military history and are looking to expand your knowledge, you might as well pass this up unless you want something to refresh your memory.
