Candidate Obama On Military Force

Waaaay back in 2007, candidate-for-President Barack Obama makes a good point regarding military force -- that could very easily be applied to the unfolding situation in Libya:
The President does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation.

As Commander-in-Chief, the President does have a duty to protect and defend the United States. In instances of self-defense, the President would be within his constitutional authority to act before advising Congress or seeking its consent.
My emphasis.

Interesting. I would hardly call Libya an instance of self-defense. So, what happens now, Mr. President?
