Germany has always had a large population, centralized location and good land (resources). They'd learned how to use those factors time and time again, and Germany became a superpower.
However, like Nebukadnezar, Germany's time in the sun is over. There are larger and more powerful countries in the world, though Germany will hold a powerful role in Europe for some time. Germans have always been able to use war to their advantage (well, until this previous century), and the world today isn't really condusive to wars of expansion, etc. which puts Germany back into the same position as most other nations of its size and power.
