We don't know who Niko House is, but according to his X handle he's the real Niko House, so take that for what it's worth. House believes that the world can move on with genuine solutions to problems once it admits that the narrative that the United States was one of the "good guys" in World War II crumbles.

Is he referring to all of the allied powers or just the United States? It sounds like it's just America.

Readers added context they thought people might want to know

To imply that the US was not one of the good guys in WWII is akin to asserting that it was the Axis Powers who instead were the good guys, but it is widely recognized that Italy, Germany, and Japan were among the most systematic perpetrators of war crimes in modern history.

Were Japan good guys for bombing Pearl Harbor?

House says in his X bio that he's a "world-renowned political s**t talker," but we don't know about world-renowned, since we'd never heard of him until now.
