However, the delays in the H-Fuel production/shipping could be sufficient for Liberty + Bretonia to get eaten, especially when the Unioners take up their usual bloody reprisal game against Kruger and Republican in the Sigmas after the situation's stabilized. The infrastructure alone is at least decades of effort, to say nothing of The Core wanting territorial concessions and other sundries.
EDIT: And even if GMG doesn't get partitioned, they still have to deal with significant material losses, reduced profits, and other reasons for their stock price to plummet. Watch them be bought out by Interspace just like Core if they somehow hold out.
