Kozh is basically just doing the thing Varis did in that one roundtable scene, of attacking the Alliance for the sole purpose of shallow point-scoring and trying to pull attention away from the fact he wants something worse.

I'm curious what he thinks about Bozja, though, which is the closest thing the game will ever get to what he wants: an admission that life under Gabranth (it should be noted not the Empire itself, just Gabranth who took a more egalitarian approach) was better for some citizens and they should probably borrow those policies, while still striving to be a self-governing independent nation.
