This article proposes a Situationist reading of Le Clezio's novels La Guerre (1970) and Les Geants (1973). Debord and Le Clezio illustrate that it is not by accident that the rise of multinational capitalism coincides with the birth of hyperreality and the post-truth era. Faced with the realistic possibility of losing their power and influence, the masters or the giants shifted their approach in order to survive. Debord and Le Clezio denounce the devastating ripple effects of this structural adaptation that would redefine society and the entirety of social relations through the skillful imposition of commercial simulacra. Even if both authors engage in hyperbolic discourse to underscore their main points, they are cognizant of what is at stake in the age of (dis-) information. Without providing any facile optimism that the road ahead will be easy, Debord and Le Clezio urge the alienated, post-modern subject to revolt. Despite the apparent limitations of the user manuals for contestation that they promote, their counter-hegemonic techniques could be a preliminary blueprint for combatting the commodification of the social, the death of the subject, and the subjugation of the populace through signs in consumer republics.
