Practice Relating to Rule 65. Perfidy
Argentina’s Law of War Manual (1969) provides that “the use of ruses and stratagems of war shall be legitimate as long as they do not imply the recourse to treason or to perfidy”, which are violations of the principle of good faith.
Argentina’s Law of War Manual (1989) states:
Those acts are perfidious, which, relying on the good faith of an adversary with the intention to betray him, lead him to believe that he is entitled to, or is obliged to accord, protection under the rules of international law …
The prohibition of employing perfidious methods does not include stratagems.
