Henry Kissinger: “This is the most volatile and complex period since World War II.”

The concern I had with the Iranian agreement was that it legitimized the eventual emergence of Iran as a nuclear power.

The challenge we face at this moment is determining what our national objectives are and how to reach them in a strategic manner.

Therefore, I think the denuclearization of North Korea must be a fundamental objective.

One's effort should be not to break up Russia, but to retain Russia in the system in some fashion.
