"Whataboutism" or "whataboutery" (as in, "but what about X?") refers to the propaganda strategy of responding to an accusation with a counter-accusation instead of offering an explanation or defense against the original accusation. It is an informal fallacy that the accused party uses to avoid accountability—whether attempting to distract by shifting the conversation's focus away from their behaviour or attempting to justify themselves by pointing to the similar behaviour (which may be true or false, but irrelevant) of their opponent or another party who is not the current subject of discussion.[1]
