[Donald] Trump was born on June 14, 1946, less than a year after the first and, thus far, only nuclear weapons were used in war.

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.

Peace is an ongoing process. It begins with the first step and it does not end. We, all of us alive today, are the gatekeepers of the future. The world we bequeath to our children and grandchildren will depend upon our success in building a more peaceful and decent world.

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.

At one point, for example, [Donald Trump] argued that he knew much more than military leaders about the pursuit and defeat of ISIS. His assuredness of his own correctness seems also rooted in arrogance reflecting his fundamental insecurity. This insecurity and his belief in his own rightness, when combined with his success at making money, leads him to be self-reliant in his decision-making, which could result in his taking risks with threatening or using nuclear weapons.

During World War II, the Nazis put their victims into gas chambers and then incinerated them in ovens. While the Nazis took their victims to the incinerators, those who possess and threaten to use nuclear weapons plan to take these weapons - these portable incinerators - to the victims.

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.
