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.

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 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.

[Donald Trump] said on MSNBC's Morning Joe program, "My primary consultant is myself." While this may make consensus easy, the range of perspective is dangerously narrow.

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.

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