Challenges to the BTWC and CWC and questions for the Pugwash CBW Working Group
The Pugwash Chemical and Biological Weapons Working Group (CBW WG) held its first virtual event on 3 October 2025. The primary objective was to gather feedback on potential topics for the WG’s development, thereby gaining a deeper understanding of the WG’s specific role in the current academic and civil society landscape. Registrants completed a small questionnaire covering both topics. Seventy-five persons from all continents, including the Middle East and North Africa, participated. Summary Jean Pascal Zanders and Lizeka Tandwa opened the meeting. Götz Neuneck, Chairperson of the Council, introduced Pugwash, its history, current activities and working methodologies. Richard Guthrie (Pugwash …
In the long shadow of Halabja
A report from Pugwash Iraq’s first international conference Thirty-seven years ago, on 16 March 1988, Iraq’s military forces hit the Kurdish town of Halabja with artillery rockets and napalm bombs, followed by sustained bombing runs releasing chemical weapons. Between three and five thousand people perished, and many thousands more suffered life-altering injuries. Almost all civilians, an estimated three-quarters of them women and children. Genetic defects resulting from their exposure to mustard and nerve agents meant that even today, their offspring too have inherited these chromosomal anomalies, making them transgenerational victims of chemical warfare. To remember the massacre, Pugwash Iraq organised …
Biological Weapons Disarmament Reaches 50
Fifty years ago, on 26 March 1975, the Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on their Destruction entered into force. The Biological and Toxin Weapons Convention (BTWC) was the first multilateral treaty to outlaw a discrete weaponry category comprehensively. No party to the treaty can develop, produce, otherwise acquire, or retain biological and toxin weapons. Nor can state parties use such weapons in any way or under any circumstances. On its 50th anniversary, 188 states are party to the BTWC. Only nine are on the outside. Four signed the …
Verification and Transparency: Learning from Project Coast
Introduction to Historical Notes, Issue #5 The fifth issue of the Historical Notes series was prepared by Professor Brian Rappert, Ms Lizeka Tandwa and Dr Chandré Gould. The South African Defence Force (SADF) established a top-secret chemical and biological weapon (CBW) programme code-named ‘Project Coast’ that operated between 1981 and 1995. Its primary aims were to develop a defensive capability for the SADF and weaponise chemical agents for crowd control, specifically during protests, and for the targeted assassinations of political activists in and outside of South Africa. The history and motives of this CBW programme, as far as it can …
“Biological weapons are banned; biological research is not”
Amid the barrage of lies accompanying Russia’s war against Ukraine, the Kremlin’s disinformation narrative that Ukraine is carrying out research to develop biological weapons stands out as particularly insidious. Not only does it attempt to justify Russia’s brutal invasion, but also discredit legitimate biological and epidemiological research worldwide, at the risk to global public health. In an interview with EUvsDisinfo, Dr. Jean-Pascal Zanders, founder of The Trench and an independent expert on disarmament questions covering chemical and biological weapons, talks about the crucial differences between legitimate biological research and the development of biological weapons and why Russia is engaging in …
Staring at disarmament’s Rubik Cube: External consensus-building at the 9th BTWC Review Conference
(Science and technology review under the BTWC, Part 3) Hungary presided over the 8th Review Conference of the Biological and Toxin Weapons Convention (BTWC) in 2016. On the first day, Ambassador György Molnár treated all delegations and other attendants to a Rubik Cube, not just because its inventor Ernö Rubik is a compatriot, but also because the participating states parties had a significant puzzle to solve. How to achieve a sufficiently relevant outcome so the convention could take a few small steps forward. A minimum expectation was an agreement on a next round of thematic intersessional Meetings of Experts (MX) …
‘Within the next 5 to 10 years, it would probably be possible…’
(Science and technology review under the BTWC, Part 1) The next series of Meetings of Experts (MX) of the Biological and Toxin Weapons Convention (BTWC) is due to take place between 30 August and 8 September, a year later than originally scheduled because of the COVID-19 pandemic. Of course, provided there is no fresh resurgence in the number of infections forcing fresh meeting and travel restrictions. If the MXs proceed as planned (albeit with reduced in-person attendance), the Meeting of States Parties (MSP) will likely convene before the end of the year. The pandemic has also pushed back the 9th …

Biological weapons: A surprise proposal from Kazakhstan worth exploring
This year the UN General Assembly (UNGA) celebrates the 75th time in session. However, the worldwide spread of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) casts dark shadow over the anniversary with some of the major global players preferring to play geopolitics when nations should unite to combat a germ that knows no borders. Unsurprisingly, many heads of state or government, ministers and other dignitaries have reflected in their statements on the pandemic and the challenges ahead. Some introduced constructive suggestions to address the factors that led to the outbreak at the end of last year. Others put forward …
