Attempting to visualize a 5th Generation [of modern warfare] from where we are now is like trying to see the outlines of the Middle Ages from the vantage point of the late Roman Empire. There is no telescope that can reach so far. We can see the barbarians on the march. In America and in Europe, we already find them inside the limes and within the legions. But what follows the chaos they bring in their wake, only the gods on Mount Olympus can see. It may be worth remembering that the last time this happened, the gods themselves died.
