This paper outlines a geopolitical, legal, and theological framework for the next phase of American hegemony precipitated by the systemic collapse of the British constitutional settlement. It argues that King Charles III’s pluralistic reinterpretation of “Defender of the Faith” constitutes a statutory and spiritual abdication, creating a structural vacuum in the Anglosphere. The paper proposes that the United States must assume custodianship of the Anglo‑Protestant institutional tradition and formally relocate global Anglican authority to American soil.
