I can remember as a young lieutenant being sent into the DMZ in the divided Vietnam, from North Vietnam.

I remember being a kid and the Vietnam War was huge and looking at Watergate.

The United Nations passed so-called sanctions again on North Korea, and they've said they 'will exercise their preemptive right to a nuclear attack.' I don't think this ought to be taken kindly.

In North Korea, grass is a vegetable eaten by the people, and they've got nuclear weapons and intercontinental ballistic missiles. So, something more stringent than what's been done to North Korea is going to have to work; otherwise, a military strike is the only option.

I would not trade you a billion dollars for the kids I led to combat in Vietnam or in fact any of the Marines that I served with for a quarter of a century.

There's the assumption being made by the national security advisers to the Obama administration that the North Korean leadership is not suicidal, that they know they will be obliterated if they attacked the United States. But I would point that everything in South Korea and Japan is well within range of what they might want to do.
