If the Danish wanted to give Switzerland the finger they could just offer all Swiss there a deal: Become a Danish citizen if you renounce your Swiss citizenship

If the Danish wanted to give Switzerland the finger they could just offer all Swiss there a deal: Become a Danish citizen if you renounce your Swiss citizenship. Though I expect a reaction that is both more level-headed and apathetic, especially from the Danish, since they have lately also been keen on the xenophobia front (re-instated border controls a few years back).
