Great negotiators never lose sight of what they are aiming at, which is not an agreement per se, but a desired outcome....Getting to yes is easy, all you have to do is roll over. It's getting what you want that's hard.

There is reason to say that negotiations with the North Koreans are not easy, they may not succeed, but they may be a way of getting to where we want to get to, limiting the capability of the North Koreans to do harm to us and our allies without the use of military force and without the risk of a major war in Northeast Asia.
