I have a lot of interests in global issues, as you know, humanity, inequity, arms control, and I continue to be active on all these issues.

Iran has the technology to produce the highly enriched uranium, which is not automatically meaning nuclear weapon.

If I could have just 1 per cent of the money spent on global armaments, no one in this world would go to bed hungry.

The gravest threat faced by the world is of an extremist group getting hold of nuclear weapons or materials.

All I know is, I think I would like to continue to do public service.

As long as some of us choose to rely on nuclear weapons, we continue to risk that these same weapons will become increasingly attractive to others.

My conscience does not permit me to run for the presidency or any other official position unless it is within a democratic framework.
