The Importance of Knowing What We Know Now

The Iraq war, 20 years later, you literally wrote the book. How do you personally feel at the anniversary? It's a very different question though if you say knowing what we know now wasn't worth it. I don't believe he was an immediate threat. But when you take away the immediacy of the threat if he doesn't have these stockpiles, I think the case for war becomes a lot more difficult.
