Pat Roberts and I both feel very strongly that when we get to Iran that we can't make the same mistakes. We have to ask the questions the hard questions before not afterwards and get the right intelligence.

I think we need to ask serious questions about how we engage militarily when we engage militarily and on what basis we engage militarily. What kind of intelligence do we have to justify a military engagement?

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.

Being an intellectual creates a lot of questions and no answers.

There's no great mystery to acting. It's a very simple thing to do but you have to work hard at it. It's about asking questions and using your imagination.
