relevant here is the work of french demographer emmanual todd
"Todd attracted attention in 1976 when, at age 25, he
predicted the fall of the Soviet Union, based on indicators such as increasing
infant mortality rates:
La chute finale: Essais sur la décomposition de la sphère Soviétique (The Final Fall: An Essay on the Decomposition of the Soviet Sphere).<a href="

however..he also published this
In
After the Empire: The Breakdown of the American Order (2001), Todd claims that many indices that he has examined (economic, demographic and ideological) show both that the
United States has outlived its status as sole
superpower, and that much of the rest of the world is becoming "modern" (declining birth rates etc.) far more rapidly than predicted.<a href="
https://en.wikipedia.org/wiki/Emmanuel_Todd#cite_note-:0-3"><span>[</span>3<span>]</span></a> Controversially, he proposes that many US foreign policy moves are designed to mask what he sees as the redundancy of the United States. In his analysis, Putin's Russia emerges as probably a more trustworthy partner in today's world than the US. The book has been much read although many of its more original ideas have been received with scepticism.
