How about a dilemma that focuses on territorial expansion or purchasing territory?
Basically, your nation is given a rare chance to expand it’s borders, or buy new land. Or even a dilemma that basically says that your nation fought in a battle, and is now given the option to have total control over the lands it has military control over.
I’m not exactly sure on what would happen, but I’d say if you accepted new land, it’d hurt your economy a bit at first, but eventually pay off. If you are given the option to have new land as the spoils of war, throw in less support from liberals.
