Meh. I mean...c'mon, this is the artist who drew Negev X Kar98k yuri-nazi concentration camp doujin back then. So the dude just being edgy as usual, nothing new here.
It's not actually difficult to see some historical relevance behind this. Back when the USSR attacked Finland in 1939, one thing that surprised them, rather lethally, was the Finnish use of the submachine gun. The Russians took some samples, and although they judged the original design of Suomi KP31 too cumbersome and expensive to manufacture, nonetheless the much easier to manufacture PPSh-41 looks quite similar and the drum mag was copied directly. Ironically enough when Germany, in turn, attacked the Soviet Union, the Germans were taken by a surprise by the heavy Soviet use of SMGs.
Let's jump decades forward, and look at AK-12. It looks more like the Finnish RK or the Israel Galil (AK variants) than the Russians' own old AK-47 (or AK-74).
I'm starting to see the root of the aggression in this comic.
