Well, it's really good to be here at the Tikva event.

I've had a long association with Tikva and very much enjoyed it.

I've had some very valuable interns and students coming out of the process,

some of whom are with us here tonight.

So it feels like a little bit like a homecoming for me to be with Tikva.

foreign issues, well, you know, I'm game. So we can talk about whatever

is in your interest. Those of you who've been to Africa know what the five, what people

the five coolest animals to kill, but in our sort of modern, more, the five animals you want to get pictures of

on your safari in Africa. And they're all dramatic animals that present big challenges of

different kinds. So that's where I get the idea of the big five. And I would strongly urge all

of you as soon as you get the chance to go to Africa and see the Big Five for yourself. It's worth doing.

So the Big Five challenges that we face, many of them come from actually one overarching transformation in our society, that our society is passing through,
