Opening and Reminder:
Trump Regime is an Existential Threat
There is no national security (inter alia) so long as we leave Donald Trump et al in power. All analysis and discussion needs to start with that acknowledgment because we can’t act as though the current moment is normal or inconsequential or explainable by rational policy and state interest processes. Things are not normal and Trump et al Regime is daily violating law, constitution, policy, and common human decency. In addition, Trump demonstrates distorted thinking marked by motivated thinking, hallucination, lying, or detachment from reality. All of this waves arms will only get worse the longer we leave the Trump et al Regime in power.

Undermining Safety to Prioritize Production
There’s NO TIME for safety oversight!
The Department of Energy (DoE) is interfering with congressionally mandated activities (violating federal law) of the Defense Nuclear Facilities Safety Board (DNFSB) (Lee 2026b, 2026c). In particular, DoE has revoked DNFSB access to information and activities; ignored DNFSB reporting requirements and communications; and violated prior agreements about access and information management with DNFSB (DNFSB & DOE 2022a, 2022b; Lee 2026a, 2026b, 2026c). At this point the DNFSB has, in bland bureaucratic language, accused (correctly) the Department of Energy of willfully misinterpreting and violating federal law and of directing its employees to do the same:
“the Board recently became aware of the March 10, 2026, DOE senior leadership memorandum, entitled Clarifying Instructions Regarding Interface with the Defense Nuclear Facilities Safety Board (Enclosure D). The Board is concerned that certain assertions and directions in this memorandum are inconsistent with the AEA (Enclosure C) and that it has been cited by DOE personnel as a basis for additional limits to existing Board access and a lack of response to new access requests” (Lee 2026b, 2).
NB The DoE Memo is *bonkers* and is attachment 4 (Lee 2026b, D1-D6).
Statements by DoE officials and site contractors have repeatedly emphasized that nuclear weapons production is the current and overriding priority: “NNSA will no longer be defined solely as a scientific stewardship organization, but an organization focused on weapons production” (Wright 2026) (see also Beck 2026; Pfeiffer 2026a & 2026b). Most frequently this overwhelming urgency of USA nuclear weapons production is justified through reference to Chinese increases in capability and deployed warheads; two-near-peer nuclear deterrence and war scenarios; and ostensible enhancements to USA power through “nuclear dominance” (Beck 2026; McNamee 2023; Miller 2023).

The DoE Memo
DoE’s recent “mem[o] for field officers” (Lee 2026c) gestures at a security-caused-state-of-exception when it argues that “DOE and NNSA have a broader public health, safety, and security mission than that delegated to the DNFSB by Congress” (p. D-5). On that basis it accuses the DNFSB of “attempted exercise of excluded functions” especially regarding “the safety of atomic weapons” (pp. D-3, D-4, & D-5). The memo gives a tendentious misinterpretation of applicable statute–and existing DNFSB-DoE memos of understanding–and then instructs employees that it is “mandatory” to restrict DNFSB access and activities to a strict interpretation of that tendentious misinterpretation of applicable statute: “Adherence to the legal framework governing the DOE-DNFSB relationship is mandatory. Activities outside the Board’s statutory limit are not authorized” (pp. D-4 & D-5). Employees are told they can ignore “real-time directions” on safety from the DNFSB and that they “shall not provide predecisional or other draft copies of standards” to the DNFSB (p. D-4). In other words, the DoE/NNSA are violating laws and agreements and ordering employees to circumscribe access and information given to the DNFSB.
Conclusion

Congress, belatedly, established the Defense Nuclear Facilities Board in 1988 because it (extremely correctly) perceived that the Department of Energy’s prioritization of nuclear weapons production put workers, the public, and the environment at risk (FRD 2009). Only after the Cold War ended were the USA public–and to an extent, lawmakers–informed of the incredible scope of nuclear weapons complex associated human exposure, environmental contamination and damage, accidents, and risky practices (DoE 1995, 1997; FRD 2009). Remediation of Hanford, for example, has been predicted to take an at least an additional 40 years and hundreds of billions of dollars (GAO 2024). Now, and again by claiming existential threats, the Trump Regime is “seeking widespread revisions to nuclear safety capabilities” (Lee 2026b, 1) while illegally thwarting mandated safety oversight. The most likely result is more of the dirty and injurious past along with increased risk that an OOPS will make a single-source-point-of-failure facility unusable.
