He’s really unclear on the concept, isn’t he? Protocols ! and II were added because there were situations that arose after Word War II that weren’t adequately covered by the original Conventions, while affirming that the original Conventions remained fully in force.

All of which is irrelevant - the terms for the detention of civilians are covered in the 1949 Conventions which the USA ratified.
