I have some questions about military internees, mostly about WWII but in any war in general.
As I understand it, if a military man was “captured” by a neutral power he was interned. This was pretty much the same as being a POW of a hostile power. Is this correct? (If I’m completely wrong about this, ignore the following questions.)
If this is true, was there ever any legal/diplomatic arguments made that a neutral power lacked the authority to hold citizens of a country whom they were not at war with as prisoners? Was internment for the duration of the war or just until the internee could be sent back to his own country? What would happen in a case like Switzerland, which was surrounded by hostile territory? Suppose somebody decided they didn’t want to go back and preferred to sit out the war in a neutral country; could they be forcibly deported?
If internees were sticking around for awhile, who paid for their upkeep? Were they kept in detention areas like POW camps or was the confinement looser? Were internees allowed to meet with other citizens from their country who weren’t internees? Were internees expected to try and escape like POW’s were? Could internees use force to escape? Could internment officers use force to prevent internees from escaping?
