Congress doesn't give the president his commander-in-chief authority. The Constitution does. Once war is declared, in two joint resolutions, the president exercises his constitutional power. You confuse this explicit constitutional power with the creation of executive branch agencies. They are not explicitly provided for in the Constitution. Apples and oranges. This is the problem. You and many others are searching for arguments to support your fears. I don't accept your fears, and your arguments aren't based on any historical or legal substance.
Wow, quite a speech.... I find it hard to believe that Will's arguments are not based in historical fact. Quite clearly our Constitution sets forth checks and balances of power...as for the instant issue, I don't think you are being truthful when proclaiming the answer is so cut and dry...or "clear"... If anything, Consitutional issues are often quite foggy, including this one. Will's interpretation is reasonable, as is the President's. It's what we have a Supreme Court for--to decide the issue.
Congress gives him the means to carry out his authority, and decides how far those means go.
