whaddaya mean, the united states is the entire world!
hell, look at every alien sighting and you have your proof.
just, yknow, ignore the 7.7 billion other people on the planet
I have never thought about the alien sighting thing. Are they really all or mostly in the US?

One could certainly note that America also spends by far the most on things like stealth bombers and fighters, or that the most common types of sightings oh-so-coincidentally end up matching the profiles of those stealth planes once they become common knowledge.
