OK, here's another example. For about 40 years, the United States and the Soviet Union engaged in a global game of nuclear chicken. The winning strategy was Mutually Assured Destruction (MAD). And it was only luck that an exchange wasn't triggered by accident.

So imagine how people in 2600 (if there are any) will see that. If anthropologists discover some artifact that brings it to general attention, anyway. "Horrific" is pretty likely, no?
