Some very interesting thoughts, my thanks to those that responded

The reason it was asked was to try and get some insight into the method of Caldari self-identification which I suppose currently might be considered as:
Deteis/Civire vs. Caldari
Megacorp. Loyal vs. State Loyal
"Old Meritocrat" vs. "New Meritocrat"
Even then it does not appear to be a black and white issue since Caldari at times seem to think in shades of grey and seem quite fine in being able to pick a little from column a and column b, or perhaps a bit more dialectal in thinking where it's a question of scope and degree. A traditionalist Civire loyal to their Mega and the Old Meritocracy might also accept certain notions of Caldari national identity, loyalty to the State and the New Meritocracy, and vice versa. Where they sit on the scale is an individual question.
In regards to the topic, perhaps it really is a question of trying to understand the notion of Caldari nationalism. In many respects I think the State was borne in the same sort of national fires as the French Revolution, Italian Risorigimento, the German unification of 1871 and the establishment of Israel in 1947. Nationalism is an extremely powerful ideology and where the Deteis and Civire fit into concepts of Caldari national identity is an important question to ponder I think.
Being Deteis or Civire appears at times to be well integrated into being Caldari to the point that in many respects they're almost inseparable so being staunchly traditional or not about being Deteis or Civire still does take away from the unified national identity of being a Caldari. If that makes any sense at all.
Granted, I would say the Deteis and Civire and an exploration of their history, culture, traditions and literature would probably also add depth to the Caldari identity.
As for State stability, I think the only thing I might add is that beyond the facade of, "For the State!" it's a very rich and I dare say extremely subtle faction with a very strong undercurrent of conflicting social, political, ideological and corporate forces that makes exploring the place very interesting and intriguing.
The trick, I think, is to view it with the same multiple shades of grey and perspectives the Caldari themselves as a whole seem to maintain.
