> worthy of a G7 membership
What makes a country "worthy" of G7 membership? Does constant war-waging disqualifies a country from G7? Unfair treatment of a minority group, perhaps?
I'd argue that expecting countries/organisations to behave like virtuous individuals would be too naïve.
Also I feel Japanese honour is more about loyalty than ethics. Trying to shame them for tolerating crime syndicates probably won't make a difference.
