This book's full title is "Invisible Armies, An Epic History of Guerrilla Warfare from Ancient Times to the Present". I must admit that I found this book a fascinating read. It is well written and a very good and easy read. The Romans were defeated by barbarians or irregular troops. Nomadic empires could inflict catastrophic costs on established states.
In fact irregular fighting goes back to tribal warfare. There seldom anything new under the sun. One thing that I did find very interesting is when Max Boot talked about the French in Algiers compared with the English in Malaysia.
Max Book has his own web site. He has written some very interesting articles. One article is about the case form cutting off aid to Egypt and another is a blog entry about what is being done to protect the Copts in Egypt.
There is a short review of this book on the Foreign Affairs web site. There is a much longer and more interesting review at the New York Times by Mark Mazower.
Gary Rosen of the Wall Street Journal does a short interview (6 minutes) with Max Boot Max Boot. Also Max Boot gives an interesting speech at Pritzker Military Library. He talks after introduction for about 35 minutes and then there is Q & A period.
On my website is how to find this book on Amazon if you care to purchase it. See Boot. Also, this book review and other books I have reviewed are on my website at Book Reviews.
