I don't think that any deal was needed: Iran was not a threat. Even if Iran were a threat, there was a very easy way to handle it - by establishing a Middle East Nuclear Weapons Free Zone, which is something that nearly everyone in the world wants.

Where are the drug cartels getting their weapons? They are being provided by the United States. Cut off that flow of arms.

...a very terrifying aspect of our society, and other societies, is the equanimity and the detachment with which sane, reasonable, sensible people can observe [war and human suffering]. I think that's more terrifying than the occasional Hitler ...or other that crop up - these people would not able to operate were it not for this apathy and equanimity - and therefore I think that it is in some sense the sane and reasonable and tolerant people who should share a very serious burden of guilt, that they very easily throw on the shoulders of others who seem more extreme and more violent.

This crazy ban on the seven states, where we can't accept immigrants, almost every analyst points out the obvious: It just increases the threat of terror. It lays the basis for terror. It's just like the atrocities in Abu Ghraib and Bagram and Guantanamo. They're the most fabulous recruiting techniques for Al Qaeda and ISIS.

Imagine an extrahuman observer looking at us. Such an extrahuman observer would be struck precisely by the uniformity of human languages, by the very slight variation from one language to another, and by the remarkable respects in which all languages are the same. And then he would notice we do not pay any attention to that because for the purpose of human life it is quite natural and appropriate just to take for granted everything that is common. We don't concern ourselves with that, all we worry about are differences.

The tendencies are considerably weaker in the natural sciences, which, for the past several centuries, have survived and flourished through such constant challenge, and therefore, at best, seek to encourage it. Serving the status quo in political and socioeconomic realms is a different matter.

Democracy has both expanded and declined over the years.
