"I don't know how long the North Korean regime can last. But we can't just wait for them to collapse, because in the meantime, they can do lasting damage to our security."

“I hope that the North Koreans understand that the conclusions that we came to are conclusions that are embedded in America's security situation.”

“We have been keeping the peace in the Asia-Pacific theater for decades now, and the essence of the rebalance is to keep that peace and stability going, of which we have been a pivotal part. You ask about India, yes it is difficult. We are two technical and military cultures that grew up on opposite sides of the fence during the Cold War.”

“We need to change because the world is changing, and we need to anticipate what is next and be there first, as the US military has always been. So, the changes in our future, I think is something that we are all completely committed to.”

“There was never a conspiracy, never a tremendous fear. This is a society which is now in its third generation of severe political repression, so that children in North Korea have several hours of political education a day. Their parents did, and their grandparents did.”

“Our nightmare, any of us, which would change the way we lived our lives, was if we thought that any moment Al Qaeda might detonate a nuclear weapon in a city anywhere in the world, because we learned that they had gotten hold of some plutonium from the North Koreans by sale, or when the North Korean regime collapsed, somebody smuggled it out.”

“The military option will remain on the table. If there is a good agreement to have, obviously it's worth waiting for and completing the negotiations.”
