Despite not having conclusive evidence, Theresa May and the corporate media have already condemned Russia. Also, even if Russia is responsible, some of the response does not make any sense.
The story May wants to tell has way too much holes to be sustainable. The involvement of the British double agent Skripal in the fake Steele dossier about Trump is likely the real story behind the incident. No international support is coming for May. The British opposition leader Corbyn was right today when he demanded that she produces evidence for her claims. A few more pushes and her house of cards will surely come down.
