Since humanity is no longer the epistemological, ontological, or moral measure of all things, then (how) should international political theorists rethink animal politics? The archive ‘When They Fight Back’ records incidences of when animals ‘fought back’. It explores ways of conceptualising resistance and the implications of broadening the concept to include non-human actors via three findings: (1) Animal conflicts are everywhere and classifying them as revolt, reaction, and resistance is a creative exercise that encourages reflections about interspecies relations; (2) Most animal/human conflicts are not treated as ‘conflicts’. Instead, they are normalised within a biopolitical discourse that seeks to reduce resistance (characterised as Animal living) in order to promote living (characterised as Human resistance). (3) If excluded, animal resistance finds its way back into literatures via ethical-aesthetic figurations, traces, and desires ‘for’ the Animal. As such, the archive stages a Clausewitzian case of escalation from resistances into total war. In open hostility towards a perceived enemy, animals fight back – and because they fight back, humanism has built its own form of resistance (i.e., politics, ethics, aesthetics, biopolitics, international relations, etc.). I conclude that Human Being (as a form of resistance) must be surrendered if the war on life itself is to end.
