The North Koreans have every intention to lie, steal and cheat as much as they can get away with and as they have been doing for decades. But they would also say we've been cheating them through the whole process or acting in bad faith.

We have no intention to let this incident preclude us from continuing those flights.

They could bring the weapon today inside a cargo container that comes to one of our ports, and the technologies that we have deployed would have a low chance of finding it.

The danger is that a terrorist like Osama bin Laden who is very motivated ... gets a bomb out of a place like Russia. [Say] some crook steals it, he sells it to Osama bin Laden, Osama bin Laden brings it to Cleveland, or Boston, or L.A., and blows it up.

My bottom line is that if the U.S. government just stands on the autopilot, just on the current trim line ... I think that it is more likely than not that we will see a nuclear bomb exploding in one of our cities in less than a decade.

You don't find people of integrity who operate in that zone.
