Ha ha ha. That passage will soon be found in the dictionary in the naïveté entry. Nagonna happen, because Num! Ber! One! & don't you dare raise fundamental questions, pinko!
Note also that globalist internationalist Bilderberg Illuminati conspirators the Council on Foreign Relations were amused (Because they hate us for our freedoms?) by this anti-American science.

New Scientist didn't notice until this month either.)
Not to worry, patriots: Even less attention than the usual none-at-all will be paid in July ("It's hot! I can't think!!") these United Snakes will still lead the "developed" world in blissful ignorance & nothing will change beyond increases in illness & early mortality. Death as early as possible being precisely what people deserve when they stick their fingers in their ears (or elsewhere, & not just their noses) and chant "We're number one!" over any dissenting voices.
