I grew up in a conservative household. That was the life of the time in Egypt: a conservative, middle-class household.

Libya is a good example of a country that has come to a realization that weapons of mass destruction threaten more than assure, and I hope that will be followed by others.

Barack Obama has injected fresh momentum into efforts - stalled for a decade - to bring about nuclear disarmament.

I think one country with nuclear weapons is one country too many.
