Union of Concerned Scientists (UCS) has published the following action alert:

This month marks the 55th anniversary of the Cuban Missile Crisis—a tense military and political standoff between the United States and the then Soviet Union in October 1962. That 13-day period is often considered the closest our country ever came to nuclear war. Unfortunately, current events make it feel like, once again, we are edging closer to catastrophe—this time with North Korea. In fact, beyond the dangerous words and saber rattling between President Trump and North Korean leader, Kim Jong Un, the Trump administration is pushing for more “usable” nuclear weapons as part of a hugely expensive plan to re-build the entire US nuclear arsenal. Just this week it was reported that President Trump told military commanders he wanted a tenfold increase in the size of the nuclear arsenal. In addition, the administration is threatening to tear up successful arms control agreements that have made us safer while taking other steps that will take our nuclear policy back decades. We need to work together to step back from the nuclear brink, reduce the risks these weapons pose, and build a more secure future—without the fear of global nuclear catastrophe.
