Quotes on civilian/military tension referencing management of modern-day COIN

Ran into this on American Future, quite an interesting quote from incoming GEN Petraeus and his 1987 doctoral thesis.

Very importantly, many in the military believe that the United States armed forces can win small wars if allowed to do so. Those who hold this view tend to believe that Vietnam was less an illustration of the limitations of American military power than an example of what happens if that power is limited and not used to best advantage. This feeling springs from conviction that the U.S. military in Vietnam were so hemmed in by restrictions that they could not accomplish their mission. The lesson for those of this persuasion, therefore, is that the military must be given a freer hand in future military operations. Even among the most fervent believers in this logic, however, there is a new recognition that the world is more intractable, and intervention with U.S. troops more problematic. . . .

The military also took from Vietnam (and the concomitant activities in the Pentagon) a heightened awareness that civilian officials are responsive to influences other than the objective conditions on the battlefield. A consequence has been an increase in the traditional military distrust of civilian political leaders. . . . While the military still accept emphatically the constitutional provision for civilian control of the armed forces, there remain from the Vietnam era nagging doubts about the abilities and motivations of politicians and those they appoint to key positions. Vietnam was a painful reminder for the military that they, not the transient occupants of high office, generally bear the heaviest burden during armed conflict.
