How does rusesabagina use the rwandan no as a way to critique first his own culture and then the international community?

In "Rusesabagina: My Life in Rwanda," Paul Rusesabagina uses the Rwandan notion of "no" to critique both his own culture and the international community's response to the genocide. He highlights how the Rwandan society's reluctance to confront difficult truths and the pervasive culture of silence contributed to the atrocities. Rusesabagina extends this critique to the international community, illustrating how their indifference and failure to intervene in Rwanda's crisis reflected a broader negligence towards human rights violations. Ultimately, he emphasizes that both cultural introspection and global accountability are necessary to prevent future tragedies.
