This is the Operation Just Cause Case Study of the Geneva Convention as it relates to current day and future prisoners of war, missing in action, and killed in action service members of the United States of America and all other countries which have acknowledged acceptance of the Geneva Conventions and the additonal Geneva Protocols. Hereinafter, the Geneva Conventions and Protocols shall be referred to as the Geneva Convention.

There are four conventions dated 12 August 1949, and two protocols, dated 8 June 1977.
Copies of each of these documents has been acquired and are offered here as HTML links below. No attempt has been made to alter these documents. 

Convention 1
  For the Amelioration of the Condition of the Wounded and Sick in Armed Forces in the Field

Convention 2
  For the Amelioration of the Condition of the Wounded and Sick and Shipwrecked Members of Armed Forces at Sea

Convention 3
  Relative to the Treatment of Prisoners of War

Convention 4
  Relative to the Protection of Civilian Persons in Time of War

Protocol 1
  Relating to the Protection of Victims of International Armed Conflicts

Protocol 2
  Relating to the Protection of Victims of Non-International Armed Conflicts

It is apparent, after reading the content and structure of the documents, that the protocols were intended to be addendums, or additions, to the conventions and not intended as replacements of same.

1. Nomenclature. Those involved in the POW/MIA issues object to the United States governments use of new term(s) currently in use by our military forces. This debate over nomenclature is what has prompted this study. If, in fact, the Geneva Convention stands as a primary source for national and international acceptance of rules of engagement and treatment of individual(s) in time of war and conflict, it would appear there is reason for alarm.

A search of the conventions and protocols results in several references to prisoner of war. There is no literal match to either killed in action or missing in action, per se.
