We have a legal and moral obligation to rid our world of nuclear tests and nuclear weapons. When we put an end to nuclear tests, we get closer to eliminating all nuclear weapons. A world free of nuclear weapons will be safer and more prosperous.

Within the U.N. itself, I have appointed a record number of women to high-level positions. I did not fill jobs with women just for the sake of it - I looked for the best possible candidate, and I found that if you strip away discrimination, the best possible candidate is often a woman.

I've found that in now having experienced what it's like to make records and just through growing up in general that you should be expressive about what's affecting you instead of trying to sing about a subject just for the sake of other people getting something from it.
