Not sure what your precise question or assertion is here. But I’d say history teaches that every populace in every country needs to be skeptical of every war salesman that demands for you to pay, in blood and/or treasure, for their war. In modern day parlance, our Founders were conspiracy theorists on the war issue, for they repeatedly admitted that wars occurred for reasons other than what was sold to the public. They openly tried to mitigate for the ease with which governments lead their subjects into war by stripping the war authority from the chief executive.
“We have already given in example one effectual check to the dog of war by transferring the power of letting him loose from the Executive to the Legislative body. . . ." (Jefferson to Madison, 1789)
“The constitution supposes, what the History of all Governments demonstrates, that the Executive is the branch of power most interested in war, and most prone to it. It has accordingly with studied care vested the question of war to the Legislature." (Madison to Jefferson, c. 1798.)
A favorite of mine is from Thomas Paine in a debate with Burke:
“It may with reason be said, that in the manner the English nation is represented, it signifies not where this right resides, whether in the Crown, or in the Parliament. War is the common harvest of all those who participate in the division and expenditure of public money, in all countries. It is the art of conquering at home: the object of it is an increase of revenue; and as revenue cannot be increased without taxes, a pretence must be made for expenditures. In reviewing the history of the English government, its wars and its taxes, a by-stander, not blinded by prejudice, nor warped by interest, would declare, that taxes were not raised to carry on wars, but that wars were raised to carry on taxes.”
Many years later, persecuted whistleblower Julian Assange echoed Paine’s sentiment:
