Strange as it may seem, the powers of the President, whether considered from the viewpoint of his powers as Executive, or his powers as Commander-in-Chief of the armed forces of the United States, important as they are, have received surprisingly little attention in treatises and commentaries on the Constitution, beyond reference to the constitutional provisions themselves. Therefore, the purpose of this study will be to analyze and invite attention not only to the "war powers" so-called, of the President, which may be exercised in time of war, but also those which relate to the initiation and termination of war, as well as the conduct of war, and to show what those powers are, their character, source from which derived, and manner in which they are exercised.
