It could be worth noting that Switzerland has significant advantages in terms of terrain -the Alps make any enemy advance a laborious and dangerous business. Until recently the Swiss mined all major roads so that in event of invasion life would be problematic for wheeled vehicles. Today, however, the Swiss appear overly relaxed and there's a significant trend towards the sort of populism that's crippled other European nations. Perhaps Swiss politicians have also been on the receiving end of Kremlin funds, as has notably occurred in the UK (Brexit was sponsored by nearly $10 million of Russian money) and in France (Marin Le Pen's ultra-right-wing party received $8 million) among many other examples.
