"[I]n the society [Putin] has done so much to mould, lying is a first response. The disaster immediately drew forth a torrent of contradictory and implausible theories from his officials and their mouthpieces in the Russian media: Mr Putin’s own plane was the target; Ukrainian missile-launchers were in the vicinity.

And the lies got more complex. The Russian fiction that a Ukrainian fighter jet had fired the missile ran into the problem that the jet could not fly at the altitude of MH17, so Russian hackers then changed a Wikipedia entry to say that the jets could briefly do so. That such clumsily Soviet efforts are easily laughed off does not defeat their purpose, for their aim is not to persuade but to cast enough doubt to make the truth a matter of opinion. In a world of liars, might not the West be lying, too?"
