Have you ever read the Federalist Papers? I had both a HS and a College Professor of History make me read them.
Some of what Jay and Hamilton said in those papers are apropos to the Constitutional power-grab by the Executive branch today.
Compare what they had to say to Bush’s theory of the unilateral Executive (aka “I am the Decider”) to what Jay and Hamilton said:
The most material points of difference are these: — First. The President will have only the occasional command of such part of the militia of the nation as by legislative provision may be called into the actual service of the Union. The king of Great Britain and the governor of New York have at all times the entire command of all the militia within their several jurisdictions. In this article, therefore, the power of the President would be inferior to that of either the monarch or the governor.
Second. The President is to be commander-in-chief of the army and navy of the United States. In this respect his authority would be nominally the same with that of the king of Great Britain, but in substance much inferior to it. It would amount to nothing more than the supreme command and direction of the military and naval forces, as first General and admiral of the Confederacy; while that of the British king extends to the declaring of war and to the raising and regulating of fleets and armies — all which, by the Constitution under consideration, would appertain to the legislature.
It is too true, however disgraceful it may be to human nature, that nations in general will make war whenever they have a prospect of getting anything by it; nay, absolute monarchs will often make war when their nations are to get nothing by it, but for the purposes and objects merely personal, such as thirst for military glory, revenge for personal affronts, ambition, or private compacts to aggrandize or support their particular families or partisans. These and a variety of other motives, which affect only the mind of the sovereign, often lead him to engage in wars not sanctified by justice or the voice and interests of his people.
