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.

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.

Given [Donald] Trump's surprising recent election as president of the United States, his fate and that of the Bomb are about to become seriously and dangerously intertwined with the fate of all humanity.

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

That so much power over the U.S. nuclear arsenal is placed in the hands of one man - any man - bodes ill for humanity, while completely undermining the war power granted to Congress in the U.S. constitution.

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.

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.
