Famous quotes related to united states:

    “The United States is not a nation to which peace is a necessity.”
    —Grover Cleveland (1837–1908)

    “Because of these convictions, I made a personal decision in the 1964 Presidential campaign to make education a fundamental issue and to put it high on the nation’s agenda. I proposed to act on my belief that regardless of a family’s financial condition, education should be available to every child in the United States—as much education as he could absorb.”
    —Lyndon Baines Johnson (1908–1973)

    “What chiefly distinguishes the daily press of the United States from the press of all other countries is not its lack of truthfulness or even its lack of dignity and honor, for these deficiencies are common to the newspapers everywhere, but its incurable fear of ideas, its constant effort to evade the discussion of fundamentals by translating all issues into a few elemental fears, its incessant reduction of all reflection to mere emotion. It is, in the true sense, never well-informed.”
    —H.L. (Henry Lewis)

    “In the United States the whites speak well of the Blacks but think bad about them, whereas the Blacks talk bad and think bad about the whites. Whites fear Blacks, because they have a bad conscience, and Blacks hate whites because they need not have a bad conscience.”
    —Friedrich Dürrenmatt (1921–1990)

    “The recognition of Russia on November 16, 1933, started forces which were to have considerable influence in the attempt to collectivize the United States.”
    —Herbert Hoover (1874–1964)
