Philosophical Historiography, Military History, and 2020s Crisis War

Military history has to date shown little interest in war periodicity.It will soon witness the confirmation or disproof of a war forecast made over thirty years ago, by a socio-political model of Anglo-American culture that predicted a major civic and war crisis for the 2020s.Extending that model beyond the scope of original authors, Neil Howe and William Strauss, this essay finds a mathematical periodicity of major war over fourteen centuries of American and English history.This periodicity similarly calculates 2025 at high probability for the start of a drift into civil conflict and/or slide into world war.Military historiography can deploy this modeling for empirically valid research without relying on dubious political agendas or philosophical axioms about national destinies or international determinisms.Philosophy of culture and social realism should encourage historiography's disciplined empirical investigations and predictions.
