Coexist with the Empire, coexist with the new order.
This is a possibility, and inevitably the trajectory for the foreseeable future.
This is what the nations believe, and it is also the perspective of the upper echelons of the Republic and the "Freedom Legion."
Faced with an Empire too powerful to defeat and too large to allow its collapse, the long-term strategy is to prepare for war, while the short-term strategy and tactical approach is coexistence—leveraging the stability provided by the new order to strengthen one's own abilities as much as possible. This is the strategy approved and implemented by all nations outside the Empire, differing only in their adjustments of details according to individual national circumstances.
Specifically, for Roland and the Republic, this can be encapsulated in one sentence: "War is inevitable, but if possible, strive for at least one generation's worth of peace."
