JIM KAVANAGH—False certainty is the ultimate fake news. It is just not true that, as she says: “There is no alternative conclusion other than the Russian state is culpable.” The falsity of this statement has been demonstrated by a slew of sources—including the developers of the alleged “Novichok” agent themselves, a thorough analysis by a former UN inspector in Iraq who worked on the destruction of Russian chemical weapons, establishment Western scientific outlets like New Scientist (“Other countries could have made ‘Russian’ nerve agent”), and the British government’s own mealy-mouthed, effective-but-unacknowledged disavowal of that conclusion.
