“In a moment when criticism shows a singular dearth of direction every man has to be a law unto himself in matters of theatre, writing, and painting. While the American Mercury and the new Ford continue to spread a thin varnish of Ritz over the whole United States there is a certain virtue in being unfashionable.”
—John Dos Passos (18961970)
“An alliance is like a chain. It is not made stronger by adding weak links to it. A great power like the United States gains no advantage and it loses prestige by offering, indeed peddling, its alliances to all and sundry. An alliance should be hard diplomatic currency, valuable and hard to get, and not inflationary paper from the mimeograph machine in the State Department.”
—Walter Lippmann (18891974)
“Canadians look down on the United States and consider it Hell. They are right to do so. Canada is to the United States what, in Dantes scheme, Limbo is to Hell.”
—Irving Layton (b. 1912)
“This morning the British Ambassador in Berlin handed the German Government a final Note stating that, unless we heard from them by 11 oclock that they were prepared at once to withdraw their troops from Poland, a state of war would exist between us. I have to tell you now that no such undertaking has been received, and that consequently this country is at war with Germany.”
—Neville Chamberlain (18691940)
“It is essential that there should be organization of labor. This is an era of organization. Capital organizes and therefore labor must organize.”
—Theodore Roosevelt (18581919)
“First in booze, first in shoes, and last in the American League.”
