Germany's situation is extremely awkward. After its failure to challenge UK and France's hegemony in WWI, Germany only nominally maintained and consolidated its position as the overlord of Europe.
Since the Franco-Prussian War, Germany has been the foremost military power on the European Continent. Although France emphasized its army as the top in Europe in pre-war propaganda, since the Franco-Prussian War, France has never once surpassed Germany militarily. In WWI, France's army firmly secured the second position in Europe.
However, this did not change the circumstances of Germany, the current overlord of Europe. The idea of seizing the vast overseas colonies of the UK and France through war was thwarted.
Germany could only continue to cultivate its original market and sphere of influence, using it as a base for external expansion, focusing on two directions: Eastern Europe and the Middle East.
