Game Design and the Geneva Convention

Cory's posted this interesting bit about Hugh Spencer, a parent who's agreed to let his 13-year old play Call of Duty, provided he reads up on the Geneva Conventions and abides by them during the course of play.

Awesome. I can't wait to hear the outcome.

I'm curious whether it's POSSIBLE to successfully finish the game when doing so. I wonder whether the designer(s) read the Geneva Convention and incorporated it into the design.

I wonder whether you can successfully finish Amerca's Army when doing the same?
