Again, I was influenced by my father, who was very much an atheist and took pride in combating the traditional or orthodox forms of Judaism, which his parents and which my mother's parents were very steeped in.

The American president has particular power. This makes Trump the most dangerous man in the world. He's equally dangerous because of his finger on the nuclear trigger and because of his mind ensconced in solipsistic reality. The two are a dreadful combination.

Yes, I've been very preoccupied with the survivor all through my work.

For anyone with the traits - of feeling himself victimized, of seeking to be the strongman who resolves everything, yet sees truth only through his own self and negates all other truth outside of it - is bound to become more malignant when he has power. Power then breeds an intensification of all this because the power can never be absolute power - to some extent it's stymied - but the isolation while in power becomes even more dangerous. Think of it as a vicious circle. The power intensifies these tendencies and the tendencies become more dangerous because of the power.

There is a movement of more people recognizing global warming as a danger, recognizing the human contribution to global warming, recognizing the necessity for doing something about it. So there's a trend in that direction, and that trend is consistent with what a climate swerve - which is, as we're both saying, a mindset.

With the nuclear threat we know that if sufficient weapons are used, human civilization - all of humankind - could be extinguished literally by "nuclear winter." So we have to see ourselves as part of the ultimate human group, just as we have to do with global warming.

There's an all-enveloping destructiveness in Donald Trump's character and in his psychological tendencies. But I've focused on what professionally I call solipsistic reality. Solipsistic reality means that the only reality he's capable of embracing has to do with his own self and the perception by and protection of his own self. And for a president to be so bound in this isolated solipsistic reality could not be more dangerous for the country and for the world. He's not psychotic, but I think ultimately this solipsistic reality will be the source of his removal from the presidency.
