- Within the MBS, we have people living on three planets, (soon agein depending on time) various space stations orbiting these planets, space stations and habitats in the asteroid belt, and the various installations (warehouses and fortresses) around the actual MWJ. A lot of dispersed stuff to all take out.
- Manticore is now much more than the MBS. Not only are the people in all those other parts of the Empire citizens, but there are a lot of actual inhabitants of the MBS currently in those other parts and with the fleet. Even if no-one survived an attack on the MBS, those other Manticorans would resettle it ASAP.
- And of course the whole GA would go after the attacker.
So Manticore would survive one way or another, and the MWJ would remain property of the Star Empire of Manticore.
Of course, if the MBS planets are rendered uninhabitable, then resettling cannot occur. How long that would take, we simply don't know. Not that it should be a problem: technology in the Honorverse should be plenty to support human space habitats with full comfort. It's a choice by the author not to dwell on those, since it seems habitable planets are plentiful (and highly correlated with wormhole termini).
The RMN itself would not be left orphan. As Chardt says, there's more to the empire than the MBS, so it could be officially based on Trevor's Star and Basilisk, for example, with a very long-term lease of the shipyards and docks offered by the Republic of Beowulf (Beowulf-Hypatia).
Economically, the SEM would take a huge downturn because the MWHJ is not the sole or even the majority source of funds to the empire's economy. The planet-based activities would simply stop, not to mention the loss of a highly-skilled population. But since the MWHJ wouldn't be lost and it is likely to be responsible for the largest chunk of the SEM's balance of trade, the SEM could afford to rebuild.
Though it's also possible that such a catastrophe causes the SEM to seek closer ties with the Republics of Haven and Beowulf, forming a tighter bond than the confederation/union that was hinted at the last chapter of UH. The loss of the second most advanced planet and the most advanced system in all of them would still be felt, but the impact would be mitigated. And there's absolutely no one who could hold a candle to the united RMN and RHN.
