When Baudrillard refers to the "precession of simulacra" in "Simulacra and Simulation", he is referring to the way simulacra have come to "precede" the real in the sense mentioned above, rather than to any "succession" of historical phases of the image. Referring to "On Exactitude in Science", he argued that just as for contemporary society the simulated copy had superseded the original object, so, too, the map had come to precede the geographic territory (c.f. Map–territory relation), e.g. the first Gulf War (which Baudrillard later used as an object demonstration): the image of war preceded real war. War comes not when it is made by sovereign against sovereign (not when killing for attritive and strategic neutralisation purposes is authorised; nor even, properly spoken, when shots are fired); rather, war comes when society is generally convinced that it is coming.
