György Friedman is an Austro-Hungarian geopolitical author whose main focus is on international relations. In the Counterfactual community, he is mainly well known for his (often questionable) predictions of the future. His first book written would be
The Coming War with Britain, which predicted a war between Germany and Great Britain as the United States entered a decline. This was would never happen, and many would go on to accuse Friedman of cashing in on the rising Anglophobia within Austria's northern neighbor at the time of it's writing, as well as simply copypasting tensions from the early Wilhelmine era onto the then present.
Later, he would go on to write the equally well known (at least, among the counterfactual community)
Next Century Which was an attempt by Friedman to predict the course of the 21st century from the year 2009. The TL;DR of that one was that Germany's European Order would remain dominant, even as the former US fragmented and the Empire of Japan finally began to buckle, with the former seeing various new states arising from the ashes while Mexico retook it's territory lost centuries beforehand. To fill the void, a South American federation would form in patagonia and Britain (again) would rise to challenge Germany. The Third Great War would see Germany team up with Mexico to take on Britain and Patagonia (who would get the recently independent Confederate States on their side somehow) and eventually win. The book would end with the rise of Eastern Europe into a new intermarium to challenge their old overlords in Berlin, potentially teaming up with the French to threaten Germany's formerly secure position dominating the European Continent.
Overall, while many find Friedman's predictions fascinating, most see them more as bad political thriller writing, especially his longterm predictions. Many also accuse him of being an anglopobe for his views regarding the United States and Great Britain, as well as his seeming distrust of Germany's French neighbors.
