William R. Richardson: “Russia needs to get tougher and they are not doing it. I think these U.N. sanctions were the strongest that we have ever…”

This was a concession in the first summit that we got nothing in return. So we should not concede that one again.

We absolutely need them to keep enforcing sanctions or the pressure on North Korea will deteriorate.

Well, success for me would be a commitment by North Korea to dismantle some--some of their weapons, missiles.

His main objective is to stay in power, more so than detente with the United States.
