Prof. Aron Bernstein Memorial
In a long and productive life in nuclear physics, Aron was an unflagging advocate for peace and nuclear disarmament, particularly among his scientific colleagues. This page will carry reports, articles, curricula and other projects and initiatives related to his priorities working for peace and nuclear disarmament.
Open letter to Science magazine:
Uphold the nuclear weapons test moratorium
The Trump administration is considering renewing nuclear weapons testing1, a move that could increase the danger of another nuclear arms race as well as an inadvertent or intentional nuclear war. Following in the long tradition of scientists opposing nuclear weapons due to their harmful effects on both humanity and the planet 2, we ask the U.S. government to desist from plans to conduct nuclear tests.
During the Cold War, the United States conducted 1030 nuclear weapons tests, more than all other nuclear-armed nations combined 3. In 1996, the United States signed the Comprehensive Test Ban Treaty (CTBT), agreeing not to conduct a nuclear weapons test of any yield 4. The United States has not yet ratified the CTBT but did spearhead the 2016 adoption of UN Security Council Resolution 2310, which calls upon all countries to uphold the object and purpose of the CTBT by not conducting nuclear tests 5.
Eight of the nine nuclear-armed states, including the five permanent members of the UN Security Council, have observed a moratorium on nuclear testing since 1998 3 4. The ninth, North Korea, responding to international pressure, stopped testing war-head detonations (as opposed to missile flights) in 2017 6. If the United States ratified the CTBT, joining the 168 countries who have already done so 4, there is a good chance that the other holdout countries would ratify the treaty as well 7.
In contrast, restarting U.S. nuclear weapons tests of any size, underground or above-ground, would give license to other countries, such as North Korea, India, and Pakistan, to resume testing. If the tests are underground, radioactive materials could leak into the local environment, including water supplies 8. If in the atmosphere, which is currently prohibited by the 1963 atmospheric test ban treaty 9, such tests would spread radioactivity, sometimes very widely 8.
Once the United States breaches the treaty, there will be no way to prevent other nations from carrying out tests of larger warheads or to control leaks into the environment and atmosphere. Even a “limited” nuclear exchange between nuclear-armed nations can cause untold local death and destruction, as well as global climate and agri-cultural catastrophes stemming from the climate impacts of smoke from fires ignited by nuclear weapons 10.
The current U.S. arsenal includes thou-sands of warheads, together capable of obliterating every major city in any country on Earth. Yet the United States has embarked on a $1.7 trillion nuclear weapons enhancement pro-gram 11, of which the proposed testing would be one small—but dangerous—component. All nations, including the United States, should to continue to reduce the number of nuclear warheads in the world’s arsenals, not increase their efficacy or develop more lethal versions.
Senator Ed Markey has recently introduced the Preserv-ing Leadership Against Nuclear Explosives Testing (PLANET) Act, which would deny funding for and thereby prevent the renewal of testing 12.
We urge the Senate to pass this bill and to ratify the CTBT immediately.
