What international agreement dictates how captor nations are expected to treat prisoners of war?

The Geneva Convention is the international agreement that specifically outlines the treatment of prisoners of war (POWs). Established to ensure humane conditions for those captured during armed conflicts, the Geneva Conventions provide comprehensive guidelines on the rights of POWs, including their treatment, the conditions of their detention, and the responsibilities of captor nations. These conventions emphasize the necessity for humane treatment, prohibiting torture and inhumane treatment, and ensuring access to medical care and communication with family members.

In contrast, the other agreements listed do not focus on the treatment of prisoners of war. The Hague Convention primarily deals with the laws and customs of war, and while it touches on some aspects of humanitarian law, it does not specifically address the treatment of POWs as thoroughly as the Geneva Convention does. The Paris Agreement focuses on climate change and environmental policy, and the Security Council Resolution pertains to actions and resolutions made by the United Nations Security Council, often in relation to maintaining international peace and security. Hence, the Geneva Convention is the correct reference for the humane treatment of prisoners of war.
