I agree with your theory on the Hyperzephyrians being Americans. I would like to add that the "fire lances" here are pretty obviously missiles, probably nuclear. To an ancient with no idea about modern warfare, a missile in the air might seem to him like a spear of fire. Besides, there's an ancient Chinese weapon known as the "fire lance" that was basically a gunpowder-propelled spear.
