I stumbled across this link describing not-so-nice conditions for Allied airmen interned in Switzerland during WWII. Complicated situation; caught between Germany and the Allies, with a lot of its politicians and officers actively sympathizing with the Nazis while others weren't so happy about it--viz. the repeated aerial conflicts with the Luftwaffe during 1940, until heavy threats from Berlin put an end to these fights.
Apparently it wasn't all skiing and cognac while waiting for the German defeat--escaping airmen were often sent to "concentration camps"--the commandant of the worst of them was tried and convicted for war crimes by the Swiss government after WWII. The guy who wrote this page also has nothing nice to say about the US military attache in Switzerland during WWII, whom he describes as a "traitor" for not standing up for American and Allied captives.
Hm, you learn something new every day.
I have heard of reports where Swiss Red Cross members would not note harshly treated service men, especially Jews or Blacks, in German POW camps because the Red Cross mebers leaned toward the Nazis and thought they were doing the right thing.
