Therefore, under our system of government although the president is personally convinced that war against a certain nation is just and morally right, he is nevertheless prohibited by our supreme law of the land from waging it unless he first secures a declaration of war from Congress. That was precisely why presidents Wilson and Roosevelt, who both believed that U.S. intervention in World Wars
I and II was right and just, nevertheless had to wait for a congressional declaration of war before entering the conflict. And the fact that later presidents have violated the declaration-of-war requirement does not operate as a grant of power for other presidents to do the same.
What about the congressional resolution that granted President Bush the power to wage war against unnamed nations and organizations that the president determines were linked to the September 11 attacks? Doesn't that constitute a congressional declaration of war?
No, it is instead a congressional grant to the president of Caesar-like powers to wage war, a grant that the Constitution does not authorize Congress to make.
Therefore, when a U.S. president wages what might otherwise be considered a just war, if he has failed to secure a congressional declaration of war, he is waging an illegal war — illegal from the standpoint of our own legal and governmental system. And when the American people support any such war, no matter how just and right they believe it is, they are standing not only against their own principles and heritage, not only against their own system of government and laws, but also against the only barrier standing between them and the tyranny of their own government — the Constitution.
