Question For Bob Woodward

Bob, I like most people appreciate the excerpts I have read from your new book, State Of Denial, about the Bush administration at war and it's disastrous consequences, including decisions made before the Iraq invasion and even what warnings weren't heeded before 9/11, but I am a little confused.

Why are we just getting this information now, so long after the fact?

The only reason I am asking is that this is your third book about Bush at war.
