As Commander-in-Chief of the Army and Navy, I have directed that all measures be taken for our defense.

Always will we remember the character of the onslaught against us. No matter how long it may take us to overcome this premeditated invasion, the American people in their righteous might will win through to absolute victory.

Hostilities exist. There is no blinking at the fact that our people, our territory and our interests are in grave danger.

With confidence in our armed forces - with the unbounded determination of our people - we will gain the inevitable triumph - so help us God.
