"At what point shall we expect the approach of danger? By what means shall we fortify against it? Shall we expect some transatlantic giant to step the Ocean, and crush us at a blow? Never.
All the armies of Europe, Asia and Africa combined, with all the treasure of the earth in their military chest could not by force take a drink from the Ohio, or make a track on the Blue Ridge, in a trial of a thousand years.
At what point then is the approach of danger to be expected? I answer, if it ever reach us, it must spring up amongst us. It cannot come from abroad. If destruction be our lot, we must ourselves be its author and finisher.
As a nation of freemen, we must live through all time, or die by suicide."
~ Abraham Lincoln, January 27, 1838
