We know that dictators are quick to choose aggression, while free nations strive to resolve differences in peace.
~ George W. Bush UN Speech Sept 2004
Allow the President to invade a neighboring nation, whenever he shall deem it necessary to repel an invasion, and you allow him to do so, whenever he may choose to say he deems it necessary for such a purpose — and you allow him to make war at pleasure. 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.’
~ Abraham Lincoln
So let us regard this as settled: what is morally wrong can never be advantageous, even when it enables you to make some gain that you believe to be to your advantage. The mere act of believing that some wrongful course of action constitutes an advantage is pernicious.
~ Marcus Tullius Cicero (106-43 B.C.)
