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.
