What I don't know is whether there is a way politically that you can beat away these, some of these populist movements because in the end I don't think they really do provide answers. They ride the anger. But they don't really have the answers. Or whether this is an experiment we're just going to have to go through first.

I think the people like myself who are in the center ground of politics and who think that center left and center right can cooperate and work together. Who don't like this sort of insurgent populism because we think it's not really going to deliver for the people, I think there's a big responsibility on us in the center to get our act together. And to work out radical but serious solutions to the problems people face.

I'm one of these people that, once you have had your election and you have elected your candidate, let's see what actually happens.

It's not that tens of millions of people all want to be violent. But they share the worldview that then, at its extreme, gives rise to the violence. And in my view, this is why this is such a global problem.

Before people crow about the absence of weapons of mass destruction, I suggest they wait a bit.

Repressive states are developing weapons that could cause destruction on a massive scale.

One of the most important things in politics is you've got to keep your mind infinitely curious and alive to what is happening differently.
