In the early 20th century, although East Africa was one of the few countries with a population exceeding one hundred million, its population size was not enough to make other countries feel threatened, after all, many European countries have populations exceeding ten million, and then there's Russia, a top power with a population of over one hundred fifty million.
Russia's population has long been the largest in Europe, but this doesn't mean its massive population terrifies other countries, as we must also consider factors like industry, defense industry, economic capability, social stability, and mobilization ability. If national power was based solely on population, the other European countries would have surrendered long ago.
