Try all of it? The thought that nations do not exist in Destiny is pure fallacy. The fallen are divided into nations. House of wolves, Kings, exiles, etc... The human forces are divided between the reef and the last city. The vex seem to be divided into at least two. And the thought that the symbols of a dead nation cannot exist in the future is faulty as well. You'll notice a lot of Roman, Greek, and Norse symbology and nomenclature in the game.
