I think you're all way overestimating the actual strength of the Outcasts, Corsairs, Wilde and Nomads. They are all relatively quite weak in terms of military strength (ignore the lolfleets of caps that each group has ingame, as they're irrelevant to storyline/lore/actual faction strength). In reality, none of these groups have the power to remotely stand up to a true assault by a house navy, least of all Gallia's navy. Outcasts would put up some of a fight, but would be utterly crushed fairly quickly. Nomads never had the power to stand against a house to begin with during the Nomad-Human war (neither did the Wilde as a subsection of the Nomads), and the Nomads suffered horrific losses during the war. The Wilde are in the same boat as the Nomads (especially after the war when Rheinland went on a purge of them), and neither group has yet recovered. Yes, I know, the Nomads fought the Order recently, but that is slightly different as the Order are right next door and also considerably weaker than Gallia (again, the Order is nowhere near as powerful in lore as portrayed by players ingame).
Even collectively they haven't a chance to stop the Gallics if they did launch an assault. IMG at worst would not get involved, or would actively help Gallia crush their hated enemies. Corsairs at best would not get involved, knowing that Gallia will fall eventually, but before they do they'll crush their hated Outcast foes or horrifically cripple them for good if nothing else. As for Kusari, it has next to no forces left so would not oppose Gallia in any way (Gallia already beat them into the ground and effectively made Kusari all but surrender), Bretonia is crippled and dying, and Liberty is in a war with a crippled Rheinland.
So really, there is nobody to stop Gallia from taking Omicron Alpha if they wanted to. If I were Gallia, I'd do it too. You don't have to keep Malta, just glass it or totally wreck everything in orbit and destroy anything attempting to land or take off, and/or blockade every jumphole in the system. The Outcasts' allies are simply too far away or not strong enough to make any difference at all.
' Wrote:We had a thread bout 80 years war, a year ago... and Vietnam, just like Afghanistan, wasn't a military defeat, unlike 80 years war. But I won't argue about GMG, since, in their lore, "cosine can be equal and higher then 4". You just can't beat that.
I can understand what you mean with the RL wars you are referring too but the case in Freelancer's war is the difference in the decisions made by the invading forces. RM invaded GMG space and persisted for 80 yrs all the way to it's very destruction with what seems to have been an unreasonable stubborness. Russia pulled out of Afghnistan in what? 10 yrs? Vietnam, didn't USA pull out in even less time then that? It appears the RL armies of Russian and USA had a better understanding of the costs they were incurring then the sci-fi leaders of Rheinland.
You are also making the common mistake of equating GMG to something with your metaphor similar to the mistake Rheinland made so long ago. In your metaphor it's best to say GMG is whatever equation that brings a total value equal or higher then 4. GMG was never just a bunch of miners in the Sigmas simply there mining it, they went there to live and hold their space and were very much entrenched. RM's own infocards bring up their admitted mistake in this past misperception.
