There's no reason to believe the us/them boundary should be drawn at the US border.

1. Many other nations contributed to the collective body of human knowledge throughout the history, which resulted in huge technological leaps (China, Muslims, and Europeans in different eras). Wanting to contain the knowledge sounds short-sighted.
