The newer books do seem to address questions that arose from reading the earlier books. It still seems to be a multiverse where astronauts and the military rule with some elitist ideas.
It just seems that way because the series focuses so heavily on Starfleet and thus on the things that Starfleet has jurisdiction over. If all you knew of America came from Black Sheep Squadron, M*A*S*H,
, you might think it was a country ruled by the military.
That's why I tried to offer a different, more civilian perspective on things in Watching the Clock
, a story told from the perspective of a government agency that has a somewhat adversarial relationship with Starfleet. Keith DeCandido's Articles of the Federation
also focuses on the civilian government of the UFP.
