In plain terms
This article considers how deepfake technology intersects with the law of armed conflict (LOAC). The author, Summer Crockett, opens with a hypothetical in which a fabricated surrender video is used to lure military forces into an ambush, illustrating how deepfakes could be weaponized in a combat setting even though such use has not yet been documented.
Crockett argues that deepfakes undermine the traditional "marketplace of ideas" theory, under which exposure to competing information was assumed to reveal the truth, because deepfake technology can now defeat authentication methods that once made fabricated content detectable.
