"In the field of national policy, the fundamental trouble with America has been, and is, that whereas their nation became in the twentieth century the most powerful and most vital nation in the world, nevertheless Americans were unable to accommodate themselves spiritually and practically to that fact. Hence they have failed to play their part as a world power—a failure which has had disastrous consequences for themselves and for all mankind. And the cure is this: to accept wholeheartedly our duty and our opportunity as the most powerful and vital nation in the world and in consequence to exert upon the world the full impact of our influence, for such purposes as we see fit and by such means as we see fit." Henry R. Luce, "The American Century," Life, February 1941.

a. initial neutrality in World War I.
b. highly restrictive immigration quotas in the early 20th century.
c. isolationism in the 1930s.
d. policies dealing with race and segregation during World War II.
