Two theories have been advanced at times when the delegation doctrine carried more of a force than it has in recent years. First, it is suggested that inasmuch as the war power is inherent in the Federal Government, and one shared by the legislative and executive branches, Congress does not really delegate legislative power when it authorizes the President to exercise the war power in a prescribed manner, a view which entirely overlooks the fact that the Constitution expressly vests the war power as a legislative power in Congress. Second, it is suggested that Congress' power to delegate in wartime is limited as in other situations but that the existence of a state of war is a factor weighing in favor of the validity of the delegation.

"The power [of delegation] is especially significant in connection with constitutional war powers under which the exercise of broad discretion as to method to be employed may be essential to an effective use of its war powers by Congress. The degree to which Congress must specify its policies and standards in order that the administrative authority granted may not be an
unconstitutional delegation of its own legislative power is not capable of precise definition. . . . Thus, while the constitutional structure and controls of our Government are our guides equally in war and in peace, they must be read with the realistic purposes of the entire instrument fully in mind."
