My sister-in-law works for a group that supports orphanages in Cairo. She and her colleagues take care of children left behind by circumstances beyond their control. They feed these children, clothe them and teach them to read.
At the International Atomic Energy Agency, my colleagues and I work to keep nuclear materials out of the reach of extremist groups. We inspect nuclear facilities all over the world, to be sure that peaceful nuclear activities are not being used as a cloak for weapons programmes.
My sister-in-law and I are working towards the same goal, through different paths: the security of the human family.
