[Donald Trump] said that he would encourage Japan and South Korea to develop their own nuclear arsenals to lower U.S. costs, and then has denied that he would encourage nuclear proliferation to allies (although he did say so).

[Donald] Trump has said that he would do away with the Iran Deal negotiated by the U.S. and five of its allies with Iran, and yet he recently backed away from vowing to scrap the Iran Deal for now.

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.

[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.

[Donald Trump] supports the modernization of the U.S. nuclear arsenal, while complaining about budget expenditures. He presumably intends to go forward with the $1 trillion nuclear modernization plan.

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.

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.
