Famous quotes containing the words grand and/or alliance:

    Unpretending mediocrity is good, and genius is glorious; but a weak flavor of genius in an essentially common person is detestable. It spoils the grand neutrality of a commonplace character, as the rinsings of an unwashed wine-glass spoil a draught of fair water.
    Oliver Wendell Holmes, Sr. (1809–1894)

    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 (1889–1974)
