I'm considering leaving several hapless foes alive with a OCC on the off chance that they DoW on me and provide some war happiness. Does anyone have any experience with this tactic? Is it more trouble than it's worth? I guess I'm wondering specifically if a OCC foe will ever DoW on me. I've had several chances to demand they leave my territory and they always seem to capitulate. I must have a 200-to-1 troops advantage over them so I'm wondering if it's coded in such a way that it's virtually impossible that they'd declare.
