Confirmation bias: classical lalala-hands-in-the-ears-denial tactic. Also, not a Russian. Tinfoil much? Besides I'm not the one who opened an account here a mere few months ago. I'm a regular on HN for 5+ years.

Now, regarding the accusation of "whataboutism", I found that it's the stupidest of knee-jerk responses. It makes looking at all sides look like some kind of error.

"Yeah, my side can kill, invade, meddle with others, bully, strong-arm, etc as it sees fit. But if your side does 1/10th of those things even when its justified, or even if I just accuse you falsely of doing them and you dare to point out that it's actually my side doing those things and worse, then I call out your whataboutism".

Instead of putting things into perspective, examining their history, the causes, the role of different players, people point the finger to a single direction (seldom to their own side's and rarely to the biggest offender), and when called out on it and get reminded of the greater state of affairs they go "oh, that's whataboutism".
