After the Nullification Crisis, then-President Andrew Jackson was asked if he had any message “for his friends in the South.” His reply was absolutely classic:
“Please give my compliments to my friends in your State and say to them, that if a single drop of blood shall be shed there in opposition to the laws of the United States, I will hang the first man I can lay my hand on engaged in such treasonable conduct, upon the first tree I can reach.”
