All the more reason to want to put finland back together.
Not exactly. You got tremendous costs associated with doing so that would most likely bankrupt the country. I'm pretty sure jingoism would be refrained even, because you'd be going in to do something expensive without the slightest bit of suggestion it'll pay off well into the long term. Because what else can Finland supply to the Swedish market it can't get already on its own, or even from mainland Europe?To add to this, Sweden was never a culture that tended toward Jingoism. If your politician says "We should put Finland back together to show our resolve!" you would get groans. To Swedes in this world, Finland is a thing to avoid.
I double checked. However wouldn't the prussian influence make switzerland less neutral in this world?
Prussian influence is probably minimal and not much beyond Switzerland watching its ass because it knows it can be invaded. Freddy isn't telling their President what to do.So not influence as much as just fear of getting steamrolled again, that happens to affect their decision-making.
