Whataboutism or whataboutery (as in "what about…?") denotes in a pejorative sense a procedure in which a critical question or argument is not answered or discussed, but retorted with a critical counter-question which expresses a counter-accusation. From a logical and argumentative point of view it is considered a variant of the tu-quoque pattern (Latin 'you too', term for a counter-accusation), which is a subtype of the ad-hominem argument. ... the tactic was "an old Soviet trick". ... "Kremlinologists of recent years call this 'whataboutism' because the Kremlin's various mouthpieces deployed the technique so exhaustively against the U.S." ... Russian whataboutism was "part of the national psyche". ... "Moscow's geopolitical whataboutism skills are unmatched"
