So, it's not looking good for the Republic
as of 3150...
Although, as mentioned elsewhere, I wonder if there might bee a twist in the tale.
There was a mention in TRO:3150 of deals being struck, in terms of what Stone has planned for the rest of that year. There had been speculation about who this might refer to - the Sea Foxes, for example.
But what if the "deal" is with none other than Alaric himself?
Perhaps Stone, after reviewing the contents of
Field Manual: 3145, and seeing the course of events as of the
TRO:3150 report, came to the conclusion that the Republic itself was doomed. Were the RAF to fight on, it would end up being overwhelmed by the four invading armed forces surrounding it - but at the same time, the high price in blood and treasure it may extract would leave Prefecture X shattered and broken, risking the kind of chaos that consumed the Terran Hegemony during the First Succession War. Only this time, with no "neutral" actor to secure the Sol system itself.
Of the four primary threats to the Republic, three - the Falcons, Confederation, and Combine - are both anathema to the RAF and to the hard-won way of life on the world involved. But while the Wolf Empire is no less deadly a threat to the Republic as an interstellar entity, Alaric's restraint over the Marik and Steiner worlds currently held by the Wolf Empire - going so far as to allow the games on Solaris VII to remain open, and to style himself as the "Archon", not Khan, of his Spheroid populace, makes him the best shot at allowing the people of Terra and the former Fortress Republic to maintain their individual liberties.
So, perhaps the plan might be to stage a Trial of Absorption on Terra itself, with the ultimate prize of humanity's homeworld at stake - but involving only a key portion of the RAF and of the Wolf Empire
touman respectively. If/when the Wolves win, they agree to absorb thee remaining RAF into the Wolf Empire/IlClan
touman, giving the resulting IlClan Wolf the resources and numbers it needs to kick the Falcons, Dracs, and Capellans out of the space around Terra.
In a sense, the Republic itself would die, but its legacy would live on, after a fashion, as a part of the IlClan.
But still, there's always the Terran Supremacy to (mis)jump over to, I suppose...
