What is your plan?
'Cuz if we're going to help the Chrystovians I don't wanna half-ass this. So at minimum we need to have enough strength to hold the line against the HoH, have an idea of how we might discourage the Cardassians from pushing and have some idea of how we'd handle it if the Cardassians escalate to Ashalla Pact-Federation war.
So far as I can tell, the best option is to build logistical infrastructure towards the Chrystovians while forming an alliance with other powers surrounding the Cardassians and have some sort of task force in one of the borderzone threatening the Cardassians if they make a move towards the Chrystovians. And... If I were the Cardassians I would find that to be an extremely aggressive act. Imagine if the HoH did something similar with the Gorn while courting the Cardassians?
Highly dependent on how the GMs react, because per Oneiros they're still discussing what the Council would say. This is realistically a political question more than a FADM question because what we do requires political backing to carry it out. If given a free hand, I see two good options to start with.
1) We start trying to deal with things diplomatically. There are members of the Pact who live fairly freely and have good quality of life. We could move to negotiate with the Cardassians using a threat of presence to make them more likely to take the diplomatic option and absorb the Chrystovians fairly peaceably in a matter that allows them to remain relatively independent. This isn't optimal for us in the sense of us wanting allies, but it does reduce the sophontian cost while not necessarily embroiling us in war.
2) We choose to grab things by the throat and make the Chrystovians too hard a target for the Cardassians. 5-6 ship TF to affiliate ASAP. Snakepit purchases of prefab fortifications and mines to ship to them to stiffen resistance. Lend-lease ConnieBs and consider a tactical ConstieB remanufacturing so we could refit and send them some of the 14 Federalized Consties that we may not end up using much. They would need crews for them but I suspect with our support they could go to a wartime economy and crew them with subpar crews; this wouldn't be ideal but they would be operating as basically mobile defense platforms to make taking systems difficult. Built up their navy to 125-150C and cover all their worlds in Reinforced Outposts with Weapons Platforms and the Cardassians either need to dedicate 250-300C of ships to punch them out or accept heavy losses, which is a significant deterrent (especially if we have fleets sitting on the borders going "go ahead and try it.") Per Oneiros 60-40 the Cardassians choose to risk war/avoid war so this is the high risk option.
I'm good with either, but it really grinds my gears to let the fash just roll over smaller powers. We know of the Bajorans and Kohbeerians (sp?) just within a relatively short time, and the latter was never mentioned again as part of the Pact, so who knows what happened to them. Probably occupied and enslaved. There could be an easy dozen more worlds that used to belong to someone and are now occupied with integration completed, or even genocided. A policy that secures the Chrystovians and pulls in the Allupii is the start to a means of containing Pact aggression.
Why? Maybe it would be better to let them become a friendly great power.
I don't see why our choice has to be "Gorn are Cardassian or Federation".
Right now, the Cardassians are trying to affiliate them. If we leave, the Cardassians grab them. Chasing off the Cardassians will likely require us to do like the HoH and break a 100pt tag, affiliate the Gorn, then break the rest of the tag when it advances to 300pt. We could just do that and not chase them any further and see if they evolve into a Great Power, but I don't really see a way to make the Cardassians stop without pulling the Gorn in ourselves. I'm open to suggestions for ways to make them a friendly independent as compared to an affiliate of either side, but I don't see how it's going to work out.
Moreover, their domestic side is nasty as fuck and I'd really like to see them not be so shitty to their population. Dickensian Nightmare is a tag of theirs after all.
