Capturing innocent citizens is just a NO, and should not be allowed

During the Vietnam War, American soldiers were taken as hostages, despite being part of the armed forces. This was a clear violation of the Geneva Conventions, which protect prisoners of war. Yet, it did not prevent such incidents. Moreover, it's worth noting that armies often consist of ordinary citizens conscripted into service, blurring the line between innocents and combatants.

This brings us to a challenging question: how can we ensure the protection of all individuals, irrespective of their affiliation, in times of conflict? I'd love to hear your thoughts or potential solutions on this matter.
