Good thing is it seems people are getting better at remembering who lied most and most recently. (Yes, that is me kind of implicitly admitting that the war against WMD in Iraq was based on lies. I want Nato but I don't want Afghanistan, Iraq etc.)
At this point, after https://en.wikipedia.org/wiki/Malaysia_Airlines_Flight_17 and after repeatedly saying they wouldn't invade Ukraine etc etc everyone should know that even if we don't always trust our own, Putin and those loyal to him are absolutely untrustworthy.
Disproving them takes far more resources than spreading, and doesn’t spread
