I thought that Switzerland's armed neutrality was well known, actually... Nobody disputes that Switzerland is fully capable of defending itself, but still, its action (or inaction) in WW2 isn't much to be proud of (neither is its mercenary tradition from before its neutrality).
And yeah, Rommel's Afrikacorps commited no war crimes, and in many cases behaved better than their Allied counterparts.
Rommel himself lectured white British prisoners on military honour for being racist and refusing to share cells with black comrades.
In my opinion, Switzerland has far better things to be proud of than the likes of Henri Guisan.
