The Biological and Toxin Weapons Convention (BWC) is neither in crisis nor at a cross roads, and hyperbole to the contrary is unhelpful. Yet it is perhaps because the BWC continues to trundle steadily along towards an undecided destination, that the period of relative calm should be exploited to bolster the Convention, to future proof the BWC and the norm against the hostile exploitation of infection that it embodies. To do this, there is a need for a more ambitious approach. The first two intersessional processes may have proved unexpectedly fruitful; however, this approach appears to have moved beyond its ‘best-before-date’ and gone stale. Accordingly, several states have proposed alternative approaches to building the BWC: France has proposed and piloted a peer review mechanism, something taken further forward by the Netherlands, Belgium and Luxembourg; the Czech Republic along with Canada and Switzerland have explored compliance assessment; Russia has proposed returning to the 1994 mandate (see discussion at Days of Future Past); and several countries, including the UK, Australia, Canada, Finland, Lithuania, Spain and the US, have constructively engaged in a debate on compliance. Although there is little agreement on exactly what should be done, there does appear to be an emerging critical mass, seeking to move beyond ‘tinkering around the edges’ and, once again, deal with the difficult topic of compliance.
