You may see this as a flip-flop on my position, but there was a little story on the Soviet invasion of Afghanistan that I thought was interesting. Before everyone goes all source-happy on me, no, I don't have any, and a quick Google isn't turning up much either. For all I know, this could be bullshit but it raises a good point. Apparently during the Soviet occupation of Afghanistan, a squad of Soviet soldiers had sporadic skirmishes with a band of Afghans. During one skirmish, the Soviet squad was able to capture a handful of Afghans. After the Soviets disarmed and restrained the soldiers, and in full view of the captured Afghans, the Soviets dipped their rounds in pig blood and began to execute every soldier save for one, who was released unarmed to return to his camp. The skirmishes on the squad stopped.
