If nukes start to really hit Switzerland then it will look pretty grim everywhere else as well. Might as well just get it over with and enjoy the light show.
I live less than 30 km from a large military base (although not in Switzerland). If we actually reach the point where someone decides to nuke that base, then I'm toast reagardless of whether I survice the blast or not.
A quick ending is preferable to slowly dying from radiation poisoning I guess...
