Well Japan’s imperialist roots are still present in the way they cultivate sectors of influence, amongst the hierarchy of elected officials. So too with Ukraine and any smaller nation with dense urban centers and gritty moral insight. Look at how the Nissan CEO got smuggled out in a suitcase to avoid prosecution and the ceasure of his ill gains. This guy had more influence that Akira Toriyama and still had to be flown to Turkey with a musical instrument.
Yet, I’d say Japan’s sanction power is on par with the United States for the foreseeable. This man had no connections to organized crime or industry there and about. He got loced for no reason other than his post-electoral personal life. The assassin had a homemade pipe weapon!? That’s a hell of a way to go out for someone as influential as he was.
