Asshole? I didn't say what America meant. In fact, I personally admire the United States because it has achieved so much in such a short time. I don't deny that Americans or American policies are smart. I remember our geography teacher in high school played a joke on us, saying that hybridization is good, such as rice, such as America. Hey hey. . . Just kidding.
