"The nub of the British government’s approach has been the shocking willingness of the corporate and state media to parrot repeatedly the lie that the nerve agent was Russian made, even after Porton Down said they could not tell where it was made and the OPCW confirmed that finding. In fact, while the Soviet Union did develop the “novichok” class of nerve agents, the programme involved scientists from all over the Soviet Union, especially Ukraine, Armenia and Georgia, as I myself learnt when I visited the newly decommissioned Nukus testing facility in Uzbekistan in 2002.
Furthermore, it was the USA who decommissioned the facility and removed equipment back to the United States. At least two key scientists from the programme moved to the United States. Formulae for several novichok have been published for over a decade. The USA, UK and Iran have definitely synthesised a number of novichok formulae and almost certainly others have done so too. Dozens of states have the ability to produce novichok, as do many sophisticated non-state actors.
As for motive, the Russian motive might be revenge, but whether that really outweighs the international opprobrium incurred just ahead of the World Cup, in which so much prestige has been invested, is unclear." Craig Murray
