Arkin has a specific goal. He believes the post-9/11 drive for secrecy has imperiled American security and democracy. Information is often classified, he writes, not because of the danger of passing information to those who would harm the United States, but in order to close down public debate about controversial activities. The intelligence failures that allowed 9/11 to occur, Arkin writes, show that safety is better achieved when the national-security establishment is subjected to oversight and scrutiny. His book caused a small sensation even before it came out and is essential reading for understanding the mechanics of the U.S. military and intelligence apparatus. --Alex Roslin
