That's a bit like asking if the United States accepts islands or prairies as states in the Union. You're confusing geography with political organization. The Federation doesn't accept planets, per se, nor star systems -- how could they? Planets are just objects; you can't accept an object, you have to accept a political entity.
I wasn't the one who decided to call it the UFP.
Yeah, but so what? It's called the United States of America, but that hasn't prevented it from accepting a polity located on an island chain in the middle of the Pacific Ocean as a state. That it cites its primary geographical feature -- planets -- in its name does not mean that the actual constituent political units of the Federation will be planets.
Well, one would hope that the Federation would only allow its constituent political units to have colonies if the people of those colonies consent to their unequal status, and if those colonists still get to vote in elections for the Federation Council and President. Certainly the U.S.'s current system of unincorporated territories--essentially communities that the U.S. conquered and to which it still denies equality under the law--should not be emulated.Obviously, my response is that the UFP would indeed accept United Earth as a member in addition to its colonies and territories, much like the U.S. has unincorporated territories even today.
Except we don't know that. We know that they were founded as Human colonies, but we do not know their current canonical status at all.To make a comparison: The Hawaiian islands are not part of the Union; the State of Hawaii is part of the Union. The planet Earth is not part of the Federation; the political entity United Earth is part of the Federation.
And you prove my point. The political entity of Earth (at least as far as canon goes and novels notwithstanding) includes Mars.
I did, because I wanted to make a point that the word "colony" is often used to describe the unofficial relationship between powerful states and the weak states they dominate and oppress. The phrase "puppet government" comes to mind. I made that point about the word "colony" (i.e., that it has several different definitions) to make a larger point--that we don't know exactly what the term "colony" means in this context.Who said anything about Haiti?I mean, what definition of "colony" are you using? Is this a description of the community's origins -- i.e., that it was founded by people who moved from Earth and began terraforming Mars? Is this a description of its legal political situation -- i.e., that it is considered a territory of the state known as United Earth but is subject to United Earth rule without possessing political equality with United Earth's other constituent entities (in the same way, that, say, the Territory of Indiana wasn't equal with the states in the Union prior to its becoming the State of Indiana, yet was still subject to rule from Washington)? Or is it a description of a de facto but not de jure relationship--say, a United Earth that dominates Mars the way the United States dominates the Republic of Haiti?
No, we just occupied it for decades and periodically send in our military to intervene whenever we decide we don't like how their internal political system is working. Make no mistake: Haiti is ruled from Washington, as surely as Alabama or North Dakota.A more apt comparison would be Puerto Rico. We don't own Haiti. We didn't plant a flag on their capital steps.
And Puerto Rico was covered under the second definition of "colony" I cited.
Well, no, we don't know that. We know that humans settled Mars and various moons in the Sol system, but we don't know what sovereign states did. The founding of United Earth has never been canonically established. It's entirely possible that, as the novels speculate, Mars and those moons were colonized before the founding of United Earth, by any number of pre-U.E. states. For all we know, the first Martian colony may have been established by the Republic of Uganda. And we have no idea what Mars's relationship to United Earth evolved to be.Because in canon, Earth settled Mars and the various moons of our system.Why assume that United Earth get to claim ownership of the entire solar system?
The fact that the canon has established nothing about Mars except that the colonies exist does not by default mean they must be U.E. colonies. The only factual statement about Mars's canonical status is "We don't know." It's just as non-canonical to say that Mars is a colony of United Earth as it is to say that Mars is independent of United Earth.Where does it state that in canon? No reference to Mars as an independent sovereign planet are listed on Memory Alpha.
The canon has established nothing about Mars except that the Martian colonies exist.
I rest my case.
