When I was young it was the CHINESES, AAAAAAARRRRRGGGGGHHHHHHH! But then they stopped themselves by developing a conscious and instituted the “One Child Policy.”
Next it was the Commies. Damn Commies were going to invade the USA but we dropped an Atomic Bomb on Cuba and Annexed Brazil to gain control of the Panama Canal and a shorter route to Hawaii. Thereby thwarting their Global Denomination.
