It may sound terrible, but I often say that the military saved me from a conventional life in the United States and I've never really thanked them for it, because I haven't exactly been pro-military in my work.

We have a duty to warn on an individual basis if we are treating someone who may be dangerous to herself or to others - a duty to warn people who are in danger from that person. We feel it's our duty to warn the country about the danger of this president. If we think we have learned something about Donald Trump and his psychology that is dangerous to the country, yes, we have an obligation to say so.

Donald Trump gives the impression that he would like to govern by decree. He has that impulse in him and he wants to be a savior, so he says, in his famous phrase, "Only I can fix it!" That's a strange and weird statement for anybody to make, but it's central to Trump's sense of self and self-presentation. And I think that has a lot to do with his identification with dictators. No matter how many they kill and no matter what else they do, they have this capacity to rule by decree without any interference by legislators or courts.

Every adult in the world has some sense that he or she might be obliterated at any time by these weapons that we have created.

Donald Trump doesn't have clear contact with reality, though I'm not sure it qualifies as a bona fide delusion. He needs things to be a certain way even though they aren't, and that's one reason he lies. There can also be a conscious manipulative element to it. When he put forward, and politically thrived on, the falsehood of President Obama's birth in Kenya, outside the United States, he was manipulating that lie as well as undoubtedly believing it in part, at least in a segment of his personality.

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.

While Donald Trump doesn't have any systematic ideology, he does have a narrative, and in that narrative, America was once a great country, it's been weakened by poor leadership, and only he can make it great again by taking over. And that's an image of himself as a strongman, a dictator. It isn't the clear ideology of being a fascist or some other clear-cut ideological figure. Rather, it's a narrative of himself as being unique and all-powerful. He believes it, though I'm sure he's got doubts about it.
