Apt analogy...I respect the right of Switzerland to be neutral, but are you claiming this status gave the Swiss citizens the ability to wander around the battlefields of WW2 unscathed? And, to make the analogy more apt...the concern is not the magical invulnerability of the Swiss, rather the Axis and Allies claiming to be Swiss in order to take advantage of that power.
To avoid this situation, why not just remove the fictional magical ability of the Swiss? They can be neutral all they want and avoid war by avoiding the battlefields (just like they did in real life).
