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.

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

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.

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."

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).

During the primaries, if another candidate criticized him, [Donald] Trump would respond with even stronger criticism toward his attacker.
