I'm not exaggerating. In fact, I wouldn't rated it 5 stars if I didn't learn many things. This book is a direct, indifference and thoroughly compilation of hard lessons by U.S. in its pursue for Imperial Unilateral Power with the means of Unnecessary War.
I like the point where the author introduces school of thought to describe consensus of Vietnam Lessons which will be later used to Iraq.
There's not much jargon here. The author is sincere to inculcate lessons to every individuals.
The book is not much long so to avoid you being bored. It is a straight forward book.
Highly recommended for Political Science like me or those who simply wants it.
