““According to a group of New England college students, writing in the year 1920, an alien was the following: "A person hostile to his country." "A person against the government." "A person who is on the opposite side." "A native of an unfriendly country." "A foreigner at war." "A foreigner who tries to do harm to the country he is in." "An enemy from a foreign land." "A person against a country." etc. . . . Yet the word alien is an unusually exact legal term, far more exact than words like sovereignty, independence, national honor, rights, defense, aggression, imperialism, capitalism, socialism, about which we readily take sides "for" or "against.””
