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.

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.

[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.

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

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.

Perhaps the singular positive of [Donald] Trump's desire to improve the deteriorating relations between the U.S. and Russia will lead to achieving progress toward a world free of nuclear weapons.

[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.
