The Trump administration has taken steps to downsize and eliminate the Department of Homeland Security Countering Weapons of Mass Destruction Office. The administration has also moved to dismantle the National Counterproliferation and Biosecurity Center and the Federal Bureau of Investigation’s Weapons of Mass Destruction Directorate.

These actions represent a significant reduction in the federal infrastructure dedicated to counter-proliferation and biosecurity. The Trump administration is actively reducing the footprint of these agencies as part of its current operational strategy.

The National Defense University downsized its Center for the Study of Weapons of Mass Destruction and moved it under the Institute for National Strategic Studies. This structural change aligns with broader adjustments across defense and security institutions.

The Air Force’s Center for Strategic Deterrence Studies was shut down in 2025 for budgetary reasons. This closure marks another instance of reduced capacity within military strategic studies programs.

The Trump administration referred to fentanyl as a weapon of mass destruction as part of its movement against drug trafficking. This designation reframes certain drug enforcement efforts within the context of weapons threats.

The consolidation and elimination of these offices follow a pattern of structural changes in counter-proliferation efforts that began over a decade ago. Congress terminated the Counterproliferation Program Advisory Committee’s annual report on activities and programs for countering proliferation in 2013. The Department of Defense folded the Defense Threat Reduction Agency’s Threat Reduction Advisory Committee in 2019.

Coordination responsibilities have shifted among military commands in recent years. The U.S. Special Operations Command took over the responsibility of coordinating counter weapons of mass destruction issues in 2018. However, the counter weapons of mass destruction conferences coordinated by the U.S. Special Operations Command were canceled after 2023. The U.S. Strategic Command hosted annual countering weapons of mass destruction symposia between 2008 and 2017, but those events concluded prior to the recent cancellations.

Why It Matters

The current elimination of multiple federal counter-proliferation offices extends a decade-long pattern of reducing dedicated infrastructure for weapons of mass destruction threats. This trend includes the prior termination of advisory committee reports, the folding of defense threat agencies, and the cessation of annual symposia hosted by military commands. These cumulative structural changes shift coordination responsibilities while decreasing the number of specialized entities focused on biosecurity and strategic deterrence.
