This chapter synthesises findings on whataboutism and tu quoque in the UN Security Council. It shows how theatrical, multi-audience performances often weaponise WA/TQ for character attacks, yet they can also clarify norm application. The core contribution is the “factworld” concept: arguments rest on promoted narratives of reality; weak factworlds incentivise WA/TQ assaults, while strong ones enable constructive clarification and reduce circular exchanges. The chapter reviews the mixed-methods design—meeting transcripts, NLP validation, interviews, and observation—then distills implications for reform: less theatrical formats, stronger oversight, and diplomatic autonomy. It outlines research agendas on rhetoric, soft power, and comparative cases.
