Here's just one nugget of gold panned from the river of wisdom that is Ambassador Chas Freeman's article about America’s Diplomatic Crisis (The United States has forfeited its capacity to pursue American interests through negotiated solutions):
Our habit of failing to define specific political objectives for our military also means that, in our case, war is less “an extension of politics by other means” (as Clausewitz prescribed) than a brutally direct way of punishing our foes linked to no clear conception of how they might take aboard the lessons we imagine they should draw from the drubbing we give them. Our chronic inattention to the terms of war termination means that U.S. triumphs on the battlefield are seldom, if ever, translated into terms that reward military victory with a stable peace.
States normally wage war in order to achieve a superior political condition, as per Clausewitz. But undefined wars against concepts or tactics such as "terror," much less wars to rid the world of evil-doers, have no end, ever.
