Here is Abraham Lincoln in a speech in 1838:
All the armies of Europe, Asia and Africa combined, with all the treasure of the earth (our own excepted) in their military chest; with a Bonaparte for a commander, 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.
As a nation of freemen today, we are courting suicide by ignoring clear and present dangers. Our elected representatives have eyes but do not see, and they have ears but do not hear. We must awaken ourselves, and then awaken them, before it is too late.
