6. Germany
What comes first to your mind when you think of Germany? Oktoberfest, beer, and sausages or classical music? Or maybe their passion for football? BMW, Audi, Mercedes, etc., — all of these great brands are coming from Germany and are the reason for the country’s great economy. Germany has a GDP of $3,466,757 million, and their military unit got a pretty good Power Index of 0.2609. Their current population is about 82.1 million people.
