The mirror universe is fascist, and sexist and racist.
The normal one, well, everything is shown to be run by a military organization, Starfleet, ranging from exploration to first contact and diplomacy. Federation ambassadors are portrayed as spoiled, clueless clows. All while attributing Starfleet a clear moral superiority.
And even shows like DS9, the Maquis angle hints at some moral dilema regarding the occupied colonies, show that obedience, following orders and some higher moral principle trump whatever pro-Maquis Starfleet personl might think. Because after all, if the heros ignore protocol or orders they never stabd against Starfleet. Overall, it is pretty militaristic in nature.
So I think we're operating on different interpretations of the term 'militaristic'.
Star Trek primarily depicts the Federations (of planets) Military on the frontier of their space.
The society within the Federation is generally a democratic one and the use of Star Fleet is not to invade.
"Starfleet's function was to explore unknown territory on the behalf of the Federation government, to defend the Federation and its allies from threats, to further Federation policies and interests throughout interstellar space, and, when applicable, to initiate first contact with newly-discovered worlds and to engage in diplomatic negotiations on the behalf of the Federation. "
"Unlike its traditional rivals who derive power from a single dominant species subjugating other races within the boundaries of their empire, the Federation's various Member States join willingly and are equals in the Federation's democratic society."
"Militarism is the belief or the desire of a government or a people that a state should maintain a strong military capability and to use it aggressively to expand national interests and/or values. It may also imply the glorification of the military and of the ideals of a professional military class and the "predominance of the armed forces in the administration or policy of the state (see also: stratocracy and military junta).... Militarism has been a significant element of the imperialist or expansionist ideologies of many nations throughout history. "
"A military junta is a government led by a committee of military leaders. The term junta means "meeting" or "committee" and originated in the national and local junta organized by the Spanish resistance to Napoleon's invasion of Spain in 1808."
National interests: Enforcing the prime directive and expanding the Federation through the discovery, and inclusion, of planets and civilisation. Also, diplomacy seems to mainly handled by starfleet, so soft power is handed over to the military. This also covers the aggressive expension bit.
Starfleet is portrayed as the defining element of the Federation. And throughout history, the military handling all aspects of civil admin was a very rare exception. Even just the majority is extemely rare. Once the military controls it, well, we are beyond a militaristic society and squarely in military dictatorship territory.
The Federation's national interests are driven by two primary objectives: the enforcement of the prime directive and the expansion of our alliance through the discovery and inclusion of planets and civilizations. These noble pursuits have formed the foundation of our society, aiming to foster peace, understanding, and cooperation among diverse species.
It is true that Starfleet, as the exploration and defense arm of the Federation, assumes a significant role in upholding these interests. Through its diplomatic efforts and scientific missions, Starfleet acts as an ambassador of the Federation, promoting peaceful relations and extending our shared values to uncharted territories. The use of soft power by Starfleet helps facilitate dialogue and cooperation, providing a platform for resolving conflicts and building alliances.
However, it is important to maintain a delicate balance between military and civilian authority. History has shown us that when the military assumes control over all aspects of civil administration, it is a rare exception and not the norm. Such a scenario tends to blur the lines between defense and governance, potentially leading to an imbalanced and potentially authoritarian society.
While Starfleet plays a crucial role in protecting the Federation and expanding its influence, it must coexist harmoniously with civilian institutions, where governance, legislation, and civilian oversight are essential. The principles of democracy, respect for individual rights, and the rule of law should guide our decision-making processes, ensuring that our society remains true to the values we hold dear.
By striking a balance between Starfleet's military capabilities and civilian administration, we preserve the essence of the Federation—a diverse, democratic alliance built on principles of exploration, cooperation, and respect. Through the concerted efforts of both civilian and military entities, we can ensure that the Federation continues to flourish without veering into the territory of a militaristic dictatorship.
> the command structure of Star Fleet mirrors the military
This. For someone with a longing for a culture that values duty, and with it, a sense of place and responsibility, a community with hierarchy, et cetera, Star Trek delivers. Today, those elements largely live within conservative America.
