While elements of culture may find their way into war, cultural expression in itself is a form of warfare. In SDFM, the Zentradi are a case in point; the series denies that they have a culture of their own (their military lifestyle in itself is a form of culture), and they are ultimately assimilated into Earth’s culture. As such, for all the “love conquers war” rhetoric that the series spouts, SDFM merely substitutes imperialism in the classic sense for cultural imperialism.
MF brings out a slightly more sophisticated take on this by having humanity appropriate elements of a foreign culture (i.e. “Aimo”) and give it new meaning in its various reincarnations, whether it be as a lullaby from mother to child, a pop song for a movie, or a form of martial music. In so doing, however, MF establishes that both humanity and the Vajra have their own distinct cultures, and lets each go their separate ways.
