Ghafi, you're missing the point. Italy invaded Ethiopia. Britain invaded Ethiopia. The Turks invaded Ethiopia. All of them took a toll on Ethiopia. Ethiopia did not invade Italy, Britain, or the Ottoman Empire.
Ethiopia had to fight for its very survival, for much of its history. Europe, on the other hand, by the 17th century, was basically safe from outsiders. Most of that time they wound up fighting themselves.
Again, the fact that Ethiopia inflicted defeats on the Europeans was that they were European embarrassments. That tells the real story, because Europe was clearly in control. Ethiopia was not.
Ethiopia has made little to no contribution to anything distinctly military (or economic either, I believe; the world doesn't exactly cater to Ethiopian economic strategies). The Ethiopians had to rely on European military formations and tactics to beat Europeans, not to mention acquire European firearms. Who had the upper hand? The Europeans. Not Ethiopia.
Now, some people like to say, "Yeah, but it's been European military advantages that make them favored." For much of the West's early history, it was considered backwards in both military and economy. For example, Persia's invasion of Greece was supposed to be a walkover. Persia's triremes at Salamis were no better than the Athenians', and the Greek hoplite was actually considered inferior for Persian contemporaries at the time. The Greeks won because their military advantage came from a cultural advantage in that everyone in Greece was relatively free, compared to a state such as Persia, where no one had a voice but the king. Citizens could vote in an assembly on pretty much everything, including how to fight wars. It was the Athenian polis that decided to abandon Athens and make a stand at Salamis. It was that same polis, along with Themistocles, that came up with the strategy that would ultimately defeat Xerxes' fleet.
Europe's military advantages came from its cultural advantages over its non-Western enemies. Over time, this translated into a distinct military advantage in technology as the West was more open to embrace new technology and use it for applied military purposes than anyone else. Non-Westerners ended up trying to imitate them by buying Western firearms or trying to incorporate their tactics, but in the end it was the cultural baggage that came with it that allowed the West to stay on top. It's why Europe ended up with the distinct military advantage.
I however, also agree that it's not Europe that makes up the world, and that Civilization does not mean "Western Civilization". It's all about bringing any civilization, any tribe, from history and leading them to stand the test of time. The more civs, the merrier.
