Every critic of the USA is whataboutism. USA just has to start a critique first, and then yell "whataboutism" when confronted with double standards. Problem solved.
But this article has nothing to do with the USA. We’re here discussing Qatar, and invoking America adds nothing to the conversation. This is the problem with whataboutism: it is the attempt to shut down the discussion of a grievance, by pointing out a grievance done elsewhere.
