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's narcissism seems to be reflected in his need to be liked and treated positively.

We all have choices. We can build walls or we can build bridges. We can give our talents to creating weapons of annihilation, as so many scientists have done, or we can work to find solutions to humanities greatest problems. Our orientation is found not only in our acts, but also in the policies we support or oppose.

The most positive policy proposal [Donald] Trump will bring to the table as president is his desire to improve and strengthen relations between the U.S. and Russia, which have deteriorated badly in recent years.

Even though [Donald] Trump is reported to not read very much and to have a limited range of experience, he is often certain that he is right and boldly asserts the correctness of his positions.

During the primaries, if another candidate criticized him, [Donald] Trump would respond with even stronger criticism toward his attacker.

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.
