Douglas Feith was the undersecretary of defense for policy in the Bush administration leading up to the Iraq war, working directly underneath Donald Rumsfeld. He provides a detailed, annotated account of the things that were being discussed, and the documents proving it. Rumsfeld loved to write things in memos, called "snowflakes" for his habit of sprinkling them everywhere, and one benefit to this is that we have a clear picture of what was going on behind the planning.

Mistakes were made, and these Feith does not sugar coat, but he presents a convincing case for Saddam as an imminent threat to national security, as well as statements from various government officials echoing this sentiment, even though they now speak differently on the subject.

This is the most comprehensive of the Iraq war books to date, of a different flavor than ones such as the one penned by Scott McClellan, which offers conjecture and hearsay and opinion, but nothing close to the precise details offered by Feith.

It's also a very interesting read, for being 500+ pages.
