I don't define national security, sir. What I do, though, is present government with options should it need to exercise those options 30 years from now. I can't predict the future. All I can do is predict where challenges will arise around the world, and at home potentially. Other things that we need to be concerned with--cruise missiles--their technology is proliferating. They were the first automatic UAVs. They were that first generation. UAVs now are very popular. Cruise missiles were that very first version. They only go one way.
The challenge with cruise missile technology is accessible now to many nations, and people are working on building those things to be fired off ships or off airplanes.
