This is exactly the purview of the red cross. They should work with the UN to house captured prisoners from both sides of a conflict obviously in separate compounds. Make sure they get good medical care. Let their families visit them. Make arrangements for prisoner swaps. Plenty of press access. With all these peaceloving weenies who keep asking why we can’t all just get along, you’d think this would already be an ongoing program.
With a program like that in place, the only thing that keeps them bound is they’ll wanna go home to fight again. If there was some sort of mechanism that could be generated that guaranteed they couldn’t fight again, POWs would become more of a processing thing than years of being abused.
That reciprocity doesn’t work here. Although Russia is caring for Ukrainian prisoners and giving them unlimited phone time with their families. Ukraine isn’t doing that as the majority of Russian prisoners have been tortured and killed. We know that from the many videos that the Ukrainian forces gleefully post of beatings, disembowelments, stabbings and castrations. Even the original Nazis more or less adhered to the Geneva convention. Rwanda or ISIS is a more fair comparison to Ukraine.
