Famous quotes containing the word country:
“I can never suppose this country so far lost to all ideas of self-importance as to be willing to grant America independence; if that could ever be adopted I shall despair of this country being ever preserved from a state of inferiority and consequently falling into a very low class among the European States.”
—George III (1738–1820)
“What a country calls its vital economic interests are not the things which enable its citizens to live, but the things which enable it to make war. Petrol is more likely than wheat to be a cause of international conflict.”
—Simone Weil (1909–1943)
