“This isn’t about extraterrestrials from other galaxies, or from a farther arm of our own, or from a moon of Saturn. That stuff is for the movies. If only our adversaries were evil ETs, I’d rejoice. But the war into which we’ve been drafted is older than Earth itself and older than the stars, and we have no choice but to give ourselves to the current battle. The war predates the universe, as do our enemies.”
