I think we ultimately ought to look to put all uranium enrichment and fuel reprocessing, if any is done, under multinational control. Those are the two technologies by which nuclear energy can be translated into nuclear weapons programmes.

When I need to see the president, I make a request directly to his scheduler. I don't have to ask anybody's permission to see the president except the president. Some weeks, I see him multiple times. Some weeks, I don't see him at all.

I don't like the term 'global warming,' because it's misleading. It implies something that's mainly about temperature, that's gradual, and that's uniform across the planet. And in fact, temperature is only one of the things that's changing.
