To nyu stud: You are correct, Pres. Wilson used the phrase “America First,” but a major part of the meaning of the term comes from the isolationists/hands off Germany crowd of the 1930’s and ’40’s.
“America First” cannot be considered a benign phrase today, because of its linkage to the anti-Semitism of the 1930’s. Someone with a brain as great – believe me – and Donald Trump thinks his brain is should come up with a phrase to describe his policy without invoking an anti-Semitic past.
