Which principle underlies the treatment of detainees according to international law?

The principle of "Respect for human dignity" is central to the treatment of detainees according to international law. This principle emphasizes the inherent value of every individual, regardless of their status or circumstances. It mandates that all detainees must be treated humanely, ensuring that their basic rights are upheld, and that they are protected from torture, inhumane treatment, and degrading conditions.

This respect for human dignity is enshrined in various international treaties and conventions, such as the Geneva Conventions, which outline the responsibilities of detaining powers regarding the treatment of individuals during armed conflicts. The application of this principle serves not only to safeguard the rights of detainees but also to maintain the moral integrity of the detaining authority and the broader legal framework of international law.

In contrast, the other options reflect approaches that do not align with international human rights standards. The idea of absolute authority of the captor negates the requirement for humane treatment, while unlimited medical intervention rights could lead to ethical conflicts regarding consent and autonomy. Prioritizing operational security over individual rights directly contradicts the obligation to treat detainees with respect and dignity.
