A focus on efficiently being colonialist and imperialist.
The issue is that as shown by the regular Garleans, there is this assumption in-universe that the conquests of Garlemald are "rightful",
irrelevant of whether they are Ascian-inspired. Whether this will be completely swept aside by the writing team is uncertain, since we can't really simulate socio-historical movements to a finicky degree in a game (nor should we). But it exists, so we can't really say that
as the evidence stands now Garleans as a whole will accept that their imperial ambitions were wrong.
