Hegemony or Survival - America's Quest For Global Dominance

Money quote:

We are entering a period of human history that may provide an answer to the question of whether it is better to be smart than stupid. The most hopeful prospect is that the question will not be answered: if it receives a definite answer, that answer can only be that humans were a kind of "biological error," using their allotted 100,000 years to destroy themselves and, in the process, much else.

The species has surely developed the capacity to do just that, and a hypothetical extraterrestrial observer might well conclude that humans have demonstrated that capacity throughout their history, dramatically in the past few hundred years, with an assault on the environment that sustains life, on the diversity of more complex organisms, and with cold and calculated savagery, on each other as well.
