Optimism is a strategy for making a better future. Because unless you believe that the future can be better, it’s unlikely you will step up and take responsibility for making it so. If you assume that there’s no hope, you guarantee that there will be no hope. If you assume that there is an instinct for freedom, there are opportunities to change things, there’s a chance you may contribute to making a better world. The choice is yours.

There are by now declassified documents from the 1950s that tells you a lot about what's going on in Egypt and we should have known it then. It's about exactly what's happening, how we can disregard public opinion as long as the dictators we support are capable of suppressing their populations. So to hell with public opinion. That's all right there in the 1950's. That's not security. That's not security of the government. That's, if anything, security from its own population. And there's a lot of that.

Sea level rise and destruction of water resources as glaciers melt alone may have horrendous human consequences.

As soon as questions of will or decision or reason or choice of action arise, human science is at a loss.

The Iranian issue I don't think has much to do with nuclear weapons frankly. Nobody is saying Iran should have nuclear weapons ­nor should anybody else. But the point in the Middle East, as distinct from North Korea, is that this is center of the world's energy resources. Originally the British and secondarily the French had dominated it, but after the Second World War, it's been a U.S. preserve. That's been an axiom of U.S. foreign policy, that it must control Middle East energy resources.

The United States is unusual among the industrial democracies in the rigidity of the system of ideological control - 'indoctrination,' we might say - exercised through the mass media.

It happened: the first 9/11, it happened on September 11, 1973, in Chile. We did it. Was that interfering or hacking a party? This record is all over the world, constantly overthrowing governments, invading, forcing people to follow what we call democracy, as in the cases I mentioned. As I say, if every charge is accurate, it's a joke, and I'm sure half the world is collapsing in laughter about this, because people outside the United States know it. You don't have to tell people in Chile about the first 9/11.
