When I came to the CIA in the mid-'90s, our graduating class of case officers was unbelievably low. Now, after years of rebuilding, our training programs and putting our best efforts to recruit the most talented men and women, we are graduating more clandestine officers than at any time in the history of the Central Intelligence Agency.

To understand a difficult topic like Iraq takes patience and care. Unfortunately, you rarely hear a patient, careful or thoughtful discussion of intelligence these days.

As a nation we have, over the past seven years, been rebuilding our intelligence with powerful capabilities that many thought we would no longer need after the Cold War. We have been rebuilding our clandestine service, our satellite and other technical collection, our analytical depth and expertise.

Here's the teaching point, if you're teaching kids about intelligence and policy: Intelligence does not absolve policymakers of responsibility to ask tough questions, and it doesn't absolve them of having curiosity about the consequences of their actions.
