Point of order on both nations: They also have protective geography that helps a great deal. The Afghani culture and being very well armed does contribute though, but IDK that we can say it's the sole reason.

Switzerland has been a neutral state during the entirety of modern aerial warfare era, so I'm going to put that less on the guns and more on the "why would I want to attack Switzerland?" attitude of the last ~100 years.

Belgium was neutral in WW1 but that didn't stop the Germans from invading it im order to try and circle around the French frontline. Switzerland being a mountainous hellhole (from a military perspective) is probably a big part of why, but it's also perfect terrain for an armed insurgency.
