Prof. Kwame Adeyemi’s follow-up to The Legitimacy Vacuum (2050) was written as the closing essay of his trilogy on the institutional transition, published five years after the Charter Review Conference and three years after the Shackleton Framework Agreement. Its opening paragraph is the passage most frequently excerpted in later historiography of the period:
“Historians will look for the moment the American century ended and will not find one, because there wasn’t one. There was a resolution suspending weapons transfers in 2035. A basing report in 2036 written in the dry language of accountants. A referendum in a country eleven thousand kilometres from Washington in 2043. A vote to move a headquarters building in 2053. None of these was a defeat. Each was simply cheaper than the alternative, and each was chosen by someone doing arithmetic rather than someone waving a flag. Empires have ended in fire before. This one ended in spreadsheets."
"The Settling”
Adeyemi’s central argument is that the period from the 2028 drone strikes to the 2055 Shackleton Framework Agreement should be read as a single 27-year process he terms “the settling” — not collapse, not decline in the traditional sense, but the redistribution of a capacity for unilateral action that had never been sustainable at the scale the mid-20th century had built it, once the specific historical conditions that had made it sustainable stopped holding. He distinguishes this from moral judgment: “This essay does not argue the arrangement deserved to end. It argues only that it was never going to survive contact with a world that could finally do the arithmetic itself, and that the arithmetic, once available to everyone, was always going to be checked.”
The Data Appendix
The essay’s most cited feature: American permanent overseas military installations, 43 in 2025, 5 in 2043, effectively 3 by 2058 (Guam, Diego Garcia, and a reduced Ramstein presence under a renegotiated NATO-successor framework); the dollar’s share of global reserve holdings, 58% in 2025, 31% in 2058, surpassed by a basket-weighted combination of the yuan, the euro, and the BRICS+ settlement instrument since 2049; UN headquarters, New York (1946–2055), Singapore and Geneva (2055–). He presents these “as the same trend line measured three different ways.”
The Closing
Adeyemi declines to name a successor arrangement: “A century that organized itself around one government’s capacity to act alone has ended. Nothing has yet organized itself around a replacement, because a Security Council that cannot be vetoed by three states acting alone is not the same thing as a world government, whatever the op-eds are currently calling it. What exists now is room. What gets built in it is the subject of the next fifty years, not this essay.”
The piece is widely credited, in later Era II retrospectives, as the point at which “the American century” entered common historical usage as a closed period rather than a live description — a periodization later canonical accounts would treat as settled, even as the political process it described had never produced a single defining moment for a textbook to cite.
