Celestia: Twilight, I suppose it never occurred to you that while we're chatting here so enjoyably, a decision is being made by Luna and the Joint Colts in the war room at the Castle. And when they realize there is no possibility of recalling the Pegasi, there will be only one course of action open: total commitment.

Twilight, do you recall what Starswirl the Bearded once said about war?

Twilight: No. I don't think I do Princess, no.

Celestia: He said war was to important to be left to the Princesses. When he said that, over a thousand years ago, he might have been right. But today, war is too important to be left to the Canterlot Elite. They have neither the time, the training, nor the inclination for strategic thought. I can no longer sit back and allow Changeling infiltration, Changeling indoctrination, Changeling subversion, and the great Changeling conspiracy to sap and impurify all of our precious bodily fluids.

Uploader Description: I asked for this years ago on the /mlp/ draw thread so it could go with the little script re-write I did above. Love that movie.
