Disarmament education: Road-testing a master’s course on CBRN dual-use technology transfer controls
From 17 until 28 June I ran an Executive Course on Export Control at the M. Narikbayev KAZGUU University in Nur-Sultan (formerly Astana), Kazakhstan. Its goal was twofold. First, it tested in a real university setting parts of a master’s course on chemical, biological, radiological and nuclear (CBRN) dual-use technology transfer controls I have been developing since February 2018. Its second purpose was to attract interest in organising the full master’s course from other Central Asian academic institutes. Set in the broader context of peace and disarmament education, the Executive Course posed considerable challenges from the perspective of educational methodology …

On suicide, riot control and ‘other peaceful purposes’ under the BTWC
In the Greater Manchester area a 16-year old boy stands trial for having tried to buy 10 milligrams of abrin on the dark web. Abrin is a toxin found in the seeds of Abrus precatorius, otherwise known as jequirity or rosary pea. UK authorities arrested him in February and have charged him under the Biological Weapons Act 1974 and Criminal Attempts Act 1981. In particular, the charge refers to the General Purpose Criterion (GPC) as framed in Article I of the Biological and Toxin Weapons Convention (BTWC) and transposed into British criminal law. As reported in The Guardian on 19 …
A very thin gruel, indeed
On 23 September, President Donald Trump addressed the UN General Assembly (UNGA). In an unexpected move, he called on the world’s nations to halt the development of biological weapons (BW). Referring to the COVID pandemic five years earlier and reckless laboratory experiments, he announced a US-led international effort to strengthen the Biological and Toxin Weapons Convention (BTWC), and proposed an artificial intelligence (AI)-driven verification system. After more than two decades of opposition, his speech seemed to indicate that Washington might embrace verification machinery for the BTWC. However, the less than two minutes he devoted to the topic contained little substance …
