I plan on discussing this letter that Lincoln wrote to William Herndon on February 15, 1848 on President Polk and the Mexican-American War. Anyone interested in placing a bet on how long it takes one of my students to bring up George Bush and Iraq?
If, today, he should choose to say he thinks it necessary to invade Canada, to prevent the British from invading us, how could you stop him? You may say to him, "I see no probability of the British invading us" but he will say to you "be silent; I see it, if you don’t."
I am looking forward to this discussion.
