Plus the LONAW is going to start their own arms race, the Dilgar are still feared amongst the galaxy and now they have reached something approaching friendship with humanity, so despite any reasurances the Earth Government gives about not tolerating Dilgar expansionism anyone near the Dilgar Empire is going to work hard to build up their defenses even more.
The LONAW will try but unfortunately will have several problems doing so. First, they are still recovering from the Dilgar War. Second, they are the League of
None Aligned Worlds, not the League of Worlds(no matter how much the Abbai wish otherwise). That's a fact that had
always screwed over their internal tech trading. Even when they want what each other has, the "bucket of crabs" mentality B5 races have, always prevented them from actually sharing despite being nominal "allies". The Drazi having the new sensors will give them something that
everyone(other then the Yolu) will want(because once the Jammer technology gets replicated, every ship that doesn't have the new sensors will instantly be rendered obsolete), but that strongly depends on whether the Drazi would actually want anything the other League races have(only thing some League races have that the Minbari don't do better are shields(both gravitic and Hyach Harmonic shields) but the Drazi are infamous for favoring attack over defense).
A third problem is that unlike the Dilgar, none of the League races have a Middle Born race(the Drakh) helping them combine their stuff( after the Shadow War, the Abbai and Brakiri governments actually did collaborate in a new ship design, only for the resulting Brivoki class advanced warship to have so many problems getting it to work that it ended up hilariously overbudget).
"Do I want to fight something whose primary reactor outmasses my fleet" seems an easy question...
"Fortified Festung" is kinda redundant, though, it's not like German kept using the same word for the princess tower and the military home like English "castle".
That depends. Is it stationary? Is it unsupported? Can I fire, evade and counterfire better then it can shoot my ships? A space station, no matter how big or well armed is often an easy target to any determined attacker with the right amount of resources and planning.
I think it would be easy for a few noble houses to bribe corrupt Earthers to get some shit.
There's a difference between getting something "off the back of a truck" and getting examples of actual Minbari
warship technology that's being held in secure locations. Remember this is Bablyon 5,
everyone has experience foiling other people's attempts to get their own advanced technology, that's why different races can have such divergent techbases rather then everything homogenizing over time.
The other thing is as I've said before, the only species outside of the Vorlons and IIRC the Yulu with any prolonged contact and positive contact with the Minbari are the Centauri and I could see Turhan who fancied himself a peacemaker maybe being persuaded to both give Minbari recovery loans and enter into a sort of mutual defense pact. Would it humiliate the warrior caste? Yes, would Bramner be dumb enough to refuse it knowing the only thing that kept the Centauri from being able to just roll them was their stealth tech? And that they've been in a nearly thousand year long competition with the Minbari dreaming of outdoing them? He might do it..it also puts the Minbari in a place where they can ensure nothing like this happens again by being more involved.
Turhan might request say..a relic from the Shadow War, or like a ship seven hundred years out of date with their main warships as part of the payment.
Truth be told, I can imagine they'd be more interested in power generation and AG tech from the Minbari than overtly their weaponry. Centauri guns were some of the best on the show, only the shadows and Vorlons consistently fucked shit up easier than the fanbros did.
The Minbari are down, they aren't out. If the Centauri ask for to much, the Minbari will shut their doors to them and there's very little the Centauri could do that wouldn't start a war with the Minbari(and be likely to drag Earth and Earth's allies into it, after all, per the treaty with Minbar, the Minbari have to
teach Earth about their technology and the EA aren't going to like someone threatening that arrangement).
Earth objecting is probably the biggest reason why the Centauri don't simply eliminate the Narn, Drazi and Dilgar before the three get too advanced(well that and Turhan's pacifism).
One which they should honestly win with the exception of the Dilgar and Earth being their equals or better. JMS really shat all over the Centauri after going to great lengths to give them a backstory that all but assured they'd end up as the big dogs without Vorlon's simping for the boneheads.
Not really? Minbari technology is
very advanced by Younger Races standards. The Minbari were more advanced then the Centauri over a thousand years ago(specifically, around where the Vree are now considering that the Vree's technology comes from them lucking out and finding a bunch of Valen War era Minbari derelicts to study and reverse engineer). It wouldprobably take the Drazi, Narn and possibly Dilgar several decades to a century to fully digest what they got, which isn't enough time for the Centauri to close the coming gap even with tech from the League, never mind reverse it. The Centauri's goal would be to try and close the future gap enough that their industrial advantage can successfully handle the rest.
