Except for the fact that Earth Starfleet is explicitly identified as being a non-military entity immediately before and after conducting what would otherwise be a military operation.
Except that this can be ignored
I don't think that it can, and :"for the love of the military" is not a compelling reason to do so.
And you managed to miss the entire point. Instead of looking at organizations and admitting to all the similarities, you have instead focused on trite arguments amounting to "the navy doesn't do this now (to which you are technically partially incorrect anyway), so Starfleet can't be a military."
Actually, I said that Starfleet is not "most like" the U.S. and British Navy. And it isn't, for the reasons I cited, not least of which because Starfleet isn't a Navy and the Navy isn't a Starfleet. It would be like you saying that the Enterprise is most similar to a submarine because it is armed with torpedoes.
Hauling things into orbit for the military doesn't in any way compare to Stafleet.
Absolutely it does, since the things being hauled into orbit are weapon systems and weapon support systems. None of those systems are THEMSELVES armed, so to the extent that military hardware can even exist in space, NASA spacecraft routinely fill that role.
And yet NASA is not a military organization.
And most of them are already military pilots and actually hold rank within the USAF or the USN.
And yet NASA is not a military organization.
No, small arms crew members carry for self defense on the off chance they land in hostile territory do not equate with armed capital ships which regularly engage in military conflict and border patrols. This comparison can't be more apples and oranges.
And what does Riker tell Krola when he shoots at an IV stand with his phaser? "It's only for self defense." Starfleet vessels are similarly equipped for precisely the same reason; we learn in ENT that starships were ALWAYS armed, even by the explicitly non-military Earth Starfleet, even at a time when no one had any reason to believe that starships would regularly encounter hostile forces in space.
So, defensive weapons carried on board the ship on the off chance that it should suddenly find itself in hostile territory... that's Starfleet in a nutshell.
That's because of treaties which forbid the militarization of space, which was a very real fear during the cold war. It's also a big reason for NASA'a start and growth.
The space shuttle had been flying for half a decade before those treaties were even conceived. If anything, they're a reason for NASA's steady
decline.
You're talking about manned spy satellites which were operated by the Soviet military.
No, they were operated by the Soviet Space Program, PART of which was under military control. Under the Russian Federation, that program is now all-civilian, and yet the military hardware developed under it remains under their control.
And yet Roskosmos is not a military organization.
You keep ignoring obvious things that Starfleet has been seen to be doing which are equivalent to functions performed by modern militaries
And you keep ignoring obvious things that NASA has been seen to be doing which are equivalent to functions performed by modern militaries. And yet NASA is not a military organization.
And why is NASA a non-military entity? Because the law says so. NASA could do exactly what it does now in exactly the same way and still be a military entity if statutory law defined it as such. But it doesn't, so it isn't.
Starfleet officers claim Starfleet isn't a military organization because, LEGALLY, it isn't. Only they know why, but only YOU know why you find it distasteful to take their word for it.
If the stigma against the militarization of space ever went away, Earth was united and thought of as a nation-state, and the system was thought of as territory that had to be protected, it's fairly obvious that a military organization would be formed to perform the function of defending this territory
Defending it from WHOM? If Earth was united under a giant nation-state, military organizations would be immediately demobilized; without the threat of international conflict, then their reason to exist in the first place has suddenly vanished. They would cling to existence in secondary/humanitarian/S.A.R. roles and would be reduced to mostly ceremonial importance; their role in actually defending their respective nation states would come to a permanent end.
Earth Starfleet WAS founded as an exploration agency as a modern successor to Roskosmos/NASA/ESA like programs. For whatever reason, no one in United Earth really believed that they had any NEED for a space defense agency, probably on the basis that in 8000 years of recorded history Earth had never been invaded by aliens and thus the need for planetary defense was virtually non-existent. They did not begin to encounter alien threats until they began to venture into space in the first place, and if exploration is the very thing that draws negative attention to Earth, who better to deal with that attention than the exploration agency itself?
