Sooner or later there will be a nuclear 9/11 [by Islamic terrorists] in an American city or that of a US ally... A terrorist nuclear attack against an American city could take many forms. A worst case scenario would be the detonation of a nuclear device within a city. Depending upon the size and sophistication of the weapon, it could kill hundreds of thousands or even millions of people.

Donald Trump and the Bomb are nearly the same age. Which of them will prove to be more destructive remains to be seen, but in combination they are terrifying.

[Donald] Trump's narcissism seems to be reflected in his need to be liked and treated positively.

That the man in question should be Donald Trump, with all his personal flaws, challenges the United States and the world as never before in human history.

On the other hand, if someone praised [Donald] Trump, he would respond with praise. This could result in creating a spiral in either a positive or negative direction. A negative spiral could potentially get out of hand, which would be alarming with regard to anyone with a hand hovering near the nuclear button.
