I haven't followed Skripal, but in the case of all attacks, I would like the fp establishment to wait for UN inspectors to render a report based on evidence before declaring whodunit.

The mainstream political opinion got us into Iraq, Vietnam, sold arms to the Indonesians in East-Timor, and concocted a nuclear missile gap with Russia that never existed. I don't think it deserves any credence except where concrete evidence is provided (and this goes for everyone else outside the mainstream too).
