I've been giving some thought to the end game scenario for the UEF.
There seems to be 2 viable strategic options, as I understand things.
1. The UEF commits sufficient fleet assets to engage and destroy a major ship and/or battlegroup of the GTVA, something around 30% of their current forces in-system. The sudden reversal against an enemy who was apparently 'on the ropes' could shift public opinion in the colonies decisively against the war. Basically, a Tet offensive.
This is essentially a one-off strategy due to the fact that UEF forces would take significant, if not critical casualties attempting such an action - which might not succeed even if tried. If the GTVA did not immediately back off, it's likely they would not retain sufficient forces to realistically defend themselves. Historically, such attempts have had mixed results.
2. This leaves Byrne's project as the remaining option. Given the bent of the story, this would seem to be the likely option to resolve things, unless our intrepid designers like putting out red herrings. The specifics are probably not able to be guessed, but in general, I can think of a few things.
A) The project will not involve direct military force. It will not be an extra fleet or giant juggernaut. Not only has this been done in-universe before, but the GTVA does have sufficient reserves to engage any realistically viable idea.
B) It will be a strategic game changing option that dramatically changes the outlook on the war.
A few thoughts of my own...
-The project is a way to artifically induce temporary system jump nodes at a destination of your choice. Being able to outmaneuver the enemy would be a gigantic advantage the UEF could use as leverage.
-The project allows direct communication with Shivan and Vishnan intelligences, allowing actual negotiation to take place. But we've been down that particular road before.
-The project replicates the star-instability trick the shivans pulled on Capella. Given the general outlook of the UEF, I find this a slim option at best.
Ideas?
