LOL! Even Saudi Arabia admitted that their citizens were involved and Osama himself admitted it. Move on.Well, about Ukraine conflict Russia is more liar, because Russia is more affected.
But about whole world conflicts USA is the winner in all known mankind history, they dont only lie more, they say bigger (hugest) lies, starting by 911 self-attacks (the world never saw a huge lie like that before).
About Ukraine conflict we have the American lie of the Nordstream blast. A piss in the face of all European "allies" (vassals).
But it's true that Russia lies are more and worst than USA lies in Ukraine conflict, one of worst Russian lies was the MH17 shoot down. So this is not the first neither worst Russian lie in the conflict.
And don't believe in the Nordstream blast pushed by the Russians blaming on U.S. or whoever. We know who did it.
