In March 2025, a troubling incident in Arkansas drew attention to the risks associated with biological weapons. Jason Kale Clampit, a tree cutter, was sentenced to eight years in prison for producing ricin, a highly toxic substance derived from castor beans. Clampit’s actions were misguided; he believed that creating this lethal agent would help deter thieves from wandering onto his property. His case underscores a critical issue: biological weapons are dangerous, even when misused by individuals without malicious intent.

This incident coincides with the 50th anniversary of the Biological Weapons Convention (BWC), a treaty that stands as a crucial barrier against the use of biological warfare. The BWC was established on March 26, 1975, as the first international agreement to ban an entire category of weapons of mass destruction. Today, 188 countries are party to the BWC, reflecting a global commitment to preventing biological warfare and protecting humanity.

The impetus for the BWC traces back to the late 1960s when U.S. leaders recognized the catastrophic potential of biological weapons. President Richard Nixon and National Security Advisor Henry Kissinger were instrumental in this shift. In 1969, Nixon announced a unilateral ban on biological weapons, understanding that their existence posed a grave threat to national and global security. Nixon believed that stockpiling such weapons could lead to their unintended use or abuse, which might destabilize international relations.

The BWC established vital norms against the development, production, and use of biological and toxin weapons. For five decades, it has successfully prevented the spread of biological agents. The BWC serves as a legal framework that enables nations to work collectively in safeguarding biological sciences and technologies for peaceful purposes.

However, as we celebrate this landmark achievement, we must also face the evolving threats that emerge in today’s world. Discussions surrounding the BWC’s anniversary have revealed significant challenges that warrant immediate attention. Recent statements from various leaders, including those from China, indicate a call for global action to strengthen the BWC framework. This statement raises eyebrows about China’s activities concerning biological agents, particularly in light of the COVID-19 pandemic.

Some analysts have posited that the origins of COVID-19 may be linked to Chinese biological research initiatives. This brings the concept of biological weapons into sharper focus. If true, the pandemic could be seen as a test of China’s capabilities in the realm of biological warfare. It suggests a troubling reality: while China publicly urges global cooperation on biological weapons, it may simultaneously be engaging in activities that challenge international norms.

Biological weapons are perceived as an even greater deterrent to Chinese aggression than nuclear weapons. The flexibility and stealth of biological agents make them particularly dangerous. As opposed to massive nuclear arsenals, biological weapons can be easier to conceal and deploy. This underscores the urgency to maintain and enhance the BWC, ensuring it evolves with the risks presented by modern science and technology.

In this context, the need to fortify the BWC against emerging threats is critical. The ninth BWC Review Conference has outlined two proposed mechanisms that could help enhance the treaty’s framework: a Science and Technology Review Mechanism and an International Cooperation and Assistance Mechanism. These mechanisms will provide the necessary tools to assess advancements in biotechnology and ensure that they are utilized responsibly.

The Science and Technology Review Mechanism would facilitate expert assessments regarding potential risks associated with bioweapons. It would enable nations to establish protocols that enhance transparency and compliance among member states. Meanwhile, the International Cooperation and Assistance Mechanism would promote knowledge sharing and the safe application of biological sciences. Such measures would provide critical support to nations, particularly those less developed, helping them to safeguard against biological threats.

As discussions about the BWC’s future unfold, the collective action of states becomes paramount. The anniversary serves as a timely reminder of the necessity for renewed commitments. Nations must work together to ensure that the treaty remains relevant to contemporary challenges. This includes strengthening biosafety measures, enhancing national capacities, and fostering regional cooperation globally.

While nearly all UN member states have joined the BWC, a few notable countries remain outside its purview: Chad, Comoros, Djibouti, Eritrea, Israel, Kiribati, Micronesia, Namibia, South Sudan, and Tuvalu. The absence of these countries poses a threat to the overall integrity and effectiveness of the BWC. All governments must actively participate in the convention to reinforce its foundations in the pursuit of a world devoid of biological weapons.

As we reflect on this significant anniversary, it’s important to acknowledge the lessons learned from the past. The BWC has played a vital role in shaping global norms around biological agents and has helped prevent the horrors of biological warfare. Yet, it must continue to evolve.

A strong and resilient BWC can not only safeguard against biological risks but also enhance health security for future generations. The call to action is clear: We must ensure that the BWC remains fit for purpose in the 21st century. As threats multiply, the stakes have never been higher.
