The methods and means to wage war have not been alien to the use of new technologies in the field of artificial intelligence, especially if we take into account the traditional interest of the States in increasing their military power. Proof of this has been the creation of Autonomous Weapons Systems: weapons with the capacity to kill without human intervention. However, there is still no official concept or clear criteria to define them, making it necessary, therefore, to analyze them in the light of International Law, especially International Humanitarian Law.
Convinced of the need to adapt Autonomous Weapons Systems to International Law (and not the other way around), the main challenges and dilemmas they face within the framework of International Law, in general, and International Humanitarian Law and International Human Rights Law, in particular, are succinctly analyzed: the need for a specific regulation or the establishment of a specific liability regime, among others.
