In a climactic moment, a member of the titular Killer 7 gang asks "What is the United States?" His companion responds "How should I know? I'm Japanese!" In one sense the summarizes the narrative of the game fairly well: complex questions are presented and answered honestly, even if not fully. The focus is less on the events of the plot, or the specifics, but on who the participants in the plot are. Who knows what the United States is--the character only knows what he is. And that's all that's really important.
