I don't think it's written from the Tevs perspective. The only thing that implies that would be the 'colleague and respected friend, Admiral Chiwetel Steele' bit. That could easily be biting sarcasm... or maybe the Elders and the Security Council are playing a deeper game then we know.
Every single other bit implies that actually attempting to engage the shivans is futile by the logic of the author. That is NOT the Tev's strategy. They seek security through military means. The UEF, and a particular admiral in general, favor pacific deployments and whatever their secret project is. This sounds like the UEF backing up their own perspective on why they CAN survive against the Shivans, purely by refusing the fight them. If the Tev's plan was to plant a big cargo container filled with Meson bombs near every jump node, and just blow them up when the Shivans appeared, then maybe I could see this being from them.
But in BP, the Tevs are planning for a military response to the 'inevitable third incursion'. It's why they want earth's industrial capacity... make more warships.
If the conclusions held in the Nary easter egg were indeed from the Tev perspective, then either a) their intel types are totally ignored or b) The security council is retarded.
I think its a UEF perspective... i.e. why its on the Nary, rather then say, hidden in the Carthage's fighter bay for example.
