In my view, stability only comes with a government that is elected by the people and works for the people.

We must abandon the unworkable notion that it is morally reprehensible for some countries to pursue weapons of mass destruction, yet morally acceptable for others to rely on them for security - and indeed to continue to refine their capacities and postulate plans for their use

If a huge number of people call for change, the government will have to react. If you want to avoid uprisings, or demonstrations, you need to respond to the peoples desperate need for change.

I still believe that any country understands that if they use nuclear weapons, they will be wiped out of existence. They could be irrational in many ways, but I don't think they're irrational to the point that they're ready to annihilate their own country.

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

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.

My father taught me that you have to stand by your principles.
