Is it really true that the UFP swore to protect the Romulans(in Una McCormack's novel the Romulans didn't even ask for the help the UFP found out about the supernova and convinced the Romulans to accept UFP aid) and not only refused to raise a second fleet but refused to participate in Romulan reconstruction? Is this really the case and Is it really so wrong for the UFP to decline to aid Romulan Free state if true.(I wouldnt be surprised if the UFP did since the RFE is generally recognized by fans as being in UFP sphere(hence the lack of Romulan Quantum singularity drives post burn) and Rafi's son does have a Romulan wife(not really evidence regarding UFP aid to RFS) and the Romulan Borg cube does have a Starfleet contingent (unclear if the RFS needed UFP and if it is scientific cooperation that is unrelated to UFP influence operations in Romulan space, it probably is but you can't be 100 percent sure. (though the Romulan excavation of the Borg cube greatly boosts local economy). Picard's ex TS aids probably falls under the same status as Rafi's son's Romulan wife, evidence of Romulan softening towards UFP but not evidence of UFP aid to RFS. The trill reporter was trolling Picard and her comment on Romulan lives mattering less(which the Romulans are obviously not UFP citizens so it is true) isn't anti Romulan racism
Could you please format your posts a bit better? Spaces between paragraphs and such. They're really hard to parse sometimes. Just one big block of text. But to answer your question, if I understood correctly, We have no idea. There hasn't been enough world building to say either way.
The Federation was fully prepared to aid the Romulans in evacuating their system, but the Utopia Planitia fleet yards - along with the rescue fleet under construction there - were destroyed by the attack force led by General Nedar (i.e. Commodore Oh). That, plus the threat of 17 member worlds to leave the Federation if the evacuation commenced, was what cauased the Federation to pull out. They simply didn't have the resources to mount another rescue attempt. There's no way that another fleet could have been built in time. That being said, after the old Romulan Star Empire fractured into all of those competing factions (all laying claim to being the 'true' Romulan Empire), I find it rather likely that at least some of those factions would be Federation friendly. Some might even pursue membership in, or at least alliance with, the Federation. The Romulan Free State is probably not one of those factions, though. Despite their name, they are little more than Tal Shiar puppets.
Why are you asking if something happened that was explicitly established in the canon to have happened? Is it really true that Federation Starfleet Captain James T. Kirk commanded the USS Enterprise NCC-1701 on a five-year mission of exploration in the 2260s? I'm not sure what you mean here? The Romulan Free State wasn't established until after the supernova led to the collapse of the Star Empire. The Federation refused to assist the Star Empire before the supernova, not the Free State. But, yes, it was really so wrong for the Federation to refuse to assist the Star Empire in evacuating its affected worlds. That's profound malice. What? On what basis is that assertion made? There is no indication whatsoever that quantum singularity drives weren't present after the Burn; quantum singularity drives obviously must require dilithium just like matter/anti-matter drives, since we know from NEM that Romulus was dependent upon dilithium mines on Remus. This makes perfect sense -- dilithium is an energy-regulation mechanism, not an energy-generation mechanism. The Burn would therefore disable or destroy ships that use quantum singularity drives just the same as ships that use matter/anti-matter drives. Well, Gabriel was born on Mars, but by 2399 he was living with his Romulan wife Pel on Freecloud, an independent world and not part of the UFP. So really all we know from this tidbit is that the Federation and whatever post-Star Empire Romulan polity Pel is from both allow their citizens to emigrate to Freecloud. If we want to try to infer anything about the relationship between the Federation and the Romulan Free State, I think it would be better to consider the fact that Laris and Zhaban both chose to emigrate to Earth and the fact that the Romulan Free State, and the fact that the Romulan Free State allowed Federation scientists to participate in the Borg Artifact Research Institute and allowed Hugh, a UFP citizen, to serve as the Institute's Executive Director. To me, that does imply a relatively more liberal immigration policy between the UFP and RFS, and implies that the RFS in particular is more open and less xenophobic than the Star Empire was. There's no way the old Star Empire would have allowed anyone other than loyal Romulans to study the Borg Artifact back in the day. The UFP scientists at the Artifact all seem to be civilians, not Starfleet. It was absolutely anti-Romulan bigotry. Which does not mean that there's a discriminatory immigration policy, but there's absolutely anti-Romulan bigotry in UFP political culture.
Picard had a plan to resue 900 million Romulans. The Zhat Vash sabotaged it (and doomed their world, because that's what idiot extremists do) by causing the Android uprising on Mars. The Federation took a step back and denied further help. Hence Nero's "the Federation stood by and did nothing!" in 2009 Star Trek. Picard retired. What's happening with the Romulan Free State and their relationship to the Federation we don't know, yet.
Not canon, but Rick Sternbach did make a diagram of the TNG Era QSD which showed dilithium being used to focus the energy being created by the singularity.
I see no reason to assume the Romulan "Free State" is any more free than those old dictatorial regimes which called themselves "democratic republics" - East Germany, Cambodia/Kampuchea, North fucking Korea, etc. I mean, the RFS has the backing of the Tal Shiar, for crying out loud. What does THAT tell you?
I mean, we don't canonically know a lot about Romulan politics. We know canonically that under the Star Empire, they had a monarchy (the "Romulan Empress" mentioned in VOY "The Q and the Grey"), that they had a Senate (TOS "Balance of Terror" et al), and that their head of government was called the Praetor (TOS "Balance of Terror," DS9 "Inter Arma Enim Silent Leges"). That's about it. For all we know, the old Romulan Star Empire might have been a democracy! The Senate might well have been popularly elected and the Praetor appointed as leader of the majority party in the Senate by the Emperor/Empress, the same way the British system works. Or it might not have been -- we have no idea. What we do know about the Romulan Free State is this: It has not chosen to maintain the existence of the Neutral Zone. It has apparently allowed Romulan citizens to emigrate to the Federation and to Freecloud. It has not prevented Romulan emigrants like Pel from marrying foreign citizens. It has allowed foreign scientists to join its Borg Artifact Reclamation program and has allowed foreign scientists access to advanced Borg technology. It has allowed a Federation citizen to serve as Executive Director of the Borg Artifact Research Institute. It has retained the backing of the Tal Shiar, but it by law no longer allows Tal Shiar agents carte blanche to seize control of any vessels or assets they wish or do whatever they wish. However, it does not appear to have totally reigned in Tal Shiar abuses, either. These signs do indicate that the Romulan Free State is probably less xenophobic than the old Star Empire; at the very least, these are objectively more liberal stances towards the rest of the galaxy than the RSE practiced. That's not to say it's a perfect bastion of classically liberal freedom, either -- but it does seem less oppressive than the Star Empire. I mean, the United States has the backing of the Central Intelligence Agency, for crying out loud. What does THAT tell you?
