There is nothing worth having that can he obtained by nuclear war - nothing material or ideological - no tradition that it can defend. It is utterly self-defeating.

Look at what President Kennedy managed to achieve during the Cuban missile crisis. If Bush had been president in 1962 do you think he would have avoided a nuclear war?

One nuclear war is going to be the last nuclear - the last war frankly if it really gets out of hand. And I just don't think we ought to be prepared to accept that sort of thing.

The surrealists and the modern movement in painting as a whole seemed to offer a key to the strange postwar world with its threat of nuclear war. The dislocations and ambiguities in cubism and abstract art as well as the surrealists reminded me of my childhood in Shanghai.

We still live with this unbelievable threat over our heads of nuclear war. I mean are we stupid? Do we think that the nuclear threat has gone that the nuclear destruction of the planet is not imminent? It's a delusion to think it's gone away.

This programme to stop nuclear by 2020 is just crazy. If there were a nuclear war and humanity were wiped out the Earth would breathe a sigh of relief.

What we have is North Korea still pursuing path to a nuclear weapon state. So the majority of people's trust in North Korea has gone down considerably.

I believe the main solution is to gain the trust of Europe and America and to remove their concerns over the peaceful nature of our nuclear industry and to assure them that there will never be a diversion to military use.

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.

Bear in mind North Korea has been the leading source a leading source of nuclear technology and of missile delivery systems to some of the world's great rogues in Iran and Syria.
