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.

A lot will depend on who [Donald] Trump chooses for key cabinet positions, but even more will depend on his consultations with his key advisor (himself).

[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).

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

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.
