CIVILIZED nations have followed those precepts, in one form or another, for about 400 years. (you could, i suppose, argue the the union armies were NOT from a civilized nation, but that wouldn't go over well with the unionist loonies here, though most of the CSA descendants would HAPPILY agree.)

Odd, stand. I was under the impression that the rebels had a penchant for shooting and hanging uniformed black Union soldiers who had been captured. Even CSA General Andrews wrote, "I cannot longer doubt that U.S. colored soldiers captured by the C.S. forces have been deliberately murdered after capture." These were not isolated incidents. It seems then, by your own definition, the confederacy isn't a "civilized nation."
