The short answer

Hugo Grotius

Quotes verified 4/4Coverage: PARTIALWhole record

Hugo Grotius believed that prisoners of war should be released upon the conclusion of peace and treated with moderation and humanity. He supported the restoration of prisoners of war to their respective sides through treaties. However, the record also indicates that captors had the power to kill prisoners, though this power was controlled by varying restrictions in different places. Confidence in this position is moderate.

3. HIS TAKE

Record coverage: PARTIAL

The record is silent on the specific treatment of prisoners of war in modern contexts and the application of international law today. However, from the principles outlined, it can be inferred that Hugo Grotius would advocate for the humane treatment of prisoners of war, their release upon the conclusion of peace, and their restoration to their former condition.

Extrapolation: Hugo Grotius would likely support the humane treatment of prisoners of war, including their release upon the conclusion of peace and their restoration to their former condition. He would also advocate for the application of treaties to ensure the restoration of prisoners of war to their respective sides.

Competing readings: The record supports the reading that Hugo Grotius believed in the humane treatment of prisoners of war and their release upon the conclusion of peace. However, it also supports the reading that captors had the power to kill prisoners, though this power was controlled by varying restrictions in different places.

Confidence: Moderate, as the record provides some direct statements on the treatment of prisoners of war but is silent on modern applications and the specific treatment of prisoners of war in contemporary contexts.
