[Donald] Trump's behavior during the presidential campaign was often erratic, seemingly based on discernable personality traits, including narcissism, arrogance, impulsiveness, and a lack of predictability.

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.

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.

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.

On January 20, 2017, Trump will be sworn in as the 45th president of the United States, and he will be given the nuclear codes and the power to launch the U.S. nuclear arsenal, which is comprised of some 7,000 nuclear weapons. A military officer will always be close to Trump, carrying the nuclear codes in a briefcase known as the "football."

[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.

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.
