Famous quotes containing the words external and/or links:
“A tempest cracked on the theatre. Quickly,
The wind beat in the roof and half the walls.
The ruin stood still in an external world.
It had been real. It was something overseas
That I remembered, something that I remembered
Overseas, that stood in an external world.”
—Wallace Stevens (1879–1955)
“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)
