Thomas Paine on pre-emptive war.

"And were America, instead of becoming an example to the Old World of good and moral government and civil manners, or, if they like it better, of gentlemanly conduct toward other nations, to set up the character of ruffian, that of word and blow, and the blow first, and thereby give the example of pulling down the little that civilization has gained upon barbarism, her independence, instead of being an honor and a blessing, would become a curse upon the world and upon herself." Thomas Paine, To the Citizens of the United States VI, 1802-1806.
