You're going to have to explain this one with a quote from him.
Baudrillard argued the Gulf War was not really a war, but rather an atrocity which masqueraded as a war. Using overwhelming airpower, the American military for the most part did not directly engage in combat with the Iraqi army, and suffered few casualties. Almost nothing was made known about Iraqi deaths. Thus, the fighting "did not really take place" from the point of view of the West. Moreover, all that spectators got to know about the war was in the form of propaganda imagery. The closely watched media presentations made it impossible to distinguish between the experience of what truly happened in the conflict, and its stylized, selective misrepresentation through simulacra.

Baudrillard's concept of "simulacrum" is connected, and perhaps more interesting, even if attempting to apply it to the world results in weird claims like this one about the Gulf war.

Just one complaint (with minor spoilers, sort of): in the end stage of the game, I walked away for a few minutes to make breakfast, and when I returned, I'd already "won" with no ability to see the final state of the game, and without any way to "replay" the counters ticking up to 100% :(
