“As to the question of who can or can’t be believed and whether anyone can be believed: no one can be believed. Where did you get the idea that President Trump trusts me or that I trust him fully? He protects the interests of the United States of America. I protect the interests of the Russian Federation.”
(The translation, from the Russian original, is mine.) In other words, Putin was saying, both of us will lie strategically. There is no such thing as the truth. Knowability is a delusion. (Masha Gessen, The New Yorker)
