In the reading Kelebogile Zvobgo (2020), "Why Race Matters in International Relations," Foreign Policy, Why does Zvobgo think that mainstream international relations theory fails to account for race, and is fundamentally built on "raced" concepts like anarchy and hierarchy? What is the historical context in which mainstream theory emerged? What are anarchy and hierarchy and what role do they play in international relations? If theory is our way of making sense of a complex world, what might "insufficient" theories based on unrepresentative samples (e.g. European experiences) leave us to miss in our study of international relations? What examples does Zvobgo offer?
