For the demographic that believes Donald Trump should be trusted with nuclear weapons, which—according to the 2016 election returns—is a minority, there is this Feb. 1 report from Time Magazine: “Since 1993, the Department of Energy has had to be ready to conduct a nuclear test within two to three years if ordered by the President. Late last year, the Trump Administration ordered the department to be ready, for the first time, to conduct a short-notice nuclear test in as little as six months. … The point, this and other sources say, would be to show Russia’s Vladimir Putin, North Korea’s Kim Jong Un, Iran’s Ayatullah Ali Khamenei and other adversaries what they are up against.

“The Trump Administration … is convinced that the best way to limit the spreading nuclear danger is to expand and advertise its ability to annihilate its enemies. In addition to putting the Nevada testing ground on notice, he has signed off on a $1.2 trillion plan to overhaul the entire nuclear-weapons complex. Trump has authorized a new nuclear warhead, the first in 34 years. He is funding research and development on a mobile medium-range missile. The new weapon, if tested or deployed, would be prohibited by a 30-year-old Cold War nuclear-forces agreement with Russia (which has already violated the agreement). And for the first time, the U.S. is expanding the scenarios under which the President would consider going nuclear to ‘significant non-nuclear strategic attacks,’ including major cyberattacks.”

The U.S. has not conducted a nuclear test in a quarter century.
