You know, people have actually changed the way they think about nuclear weapons now, post-Cold War, post-9/11. The threat of nuclear weapons is not so much Russia attacking the United States, China. It's not a state-to-state - it's obviously terrorism; it's proliferation.

We are categorically against proliferation of nuclear weapons.

I have come to believe that a nuclear Iran is not a threat but a benefit to humankind as it may well provide a much needed deterrent to the U.S. and Israel’s unrestrained use of military action and terrorism and their continuing quest for dominance and hegemony in the Middle East.

What are the implications of a China that may be on nuclear parity with the United States?

In the 1990s, the United States offered to help North Korea with its energy needs if it gave up its nuclear weapons programme.
