Abraham Lincoln and a Preemptive War

This comes from Andrew Sullivan and is a letter from Abraham Lincoln on why the President is not authorized to start a pre-emptive War, or invade another country without Congressional approve.

"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 purpose, and you allow him to make war at pleasure. Study to see if you can fix any limit to his power in this respect, after having given him so much as you propose. If to-day 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.'

"The provision of the Constitution giving the war making power to Congress was dictated, as I understand it, by the following reasons: Kings had always been involving and impoverishing their people in wars, pretending generally, if not always, that the good of the people was the object. This our convention understood to be the most oppressive of all kingly oppressions, and they resolved to so frame the Constitution that no one man should hold the power of bringing this oppression upon us. But your view destroys the whole matter, and places our President where kings have always stood," - Abraham Lincoln, in a letter to William H. Herndon, Feb. 15, 1848.

Talk about a president who understands his role in the government as the founding fathers had inteneded. What a refreshing (if not 150 years too late) view from a sitting president.
