In The Journal of The Historical Society, Bertram Wyatt-Brown wrote an article: "The Ethic of Honor in National Crises: The Civil War, Vietname, Iraq, and the Southern Factor".
It's basically about how Southern honor in the United States has fueled conflicts that otherwise had no rational basis.
Here's a taste from the article:
In all three conflicts to be discussed--Civil War, Vietnam, and Iraq--similarities in the justifications proposed, the executions of warfare, and the outcomes are tragically evident. Some of these parallels bear the imprint of a sectional culture long noted for its resort to arms and violence. In all three wars, the heads of governments were deeply immersed in the ethos of the South. The three chief executives hailed from the Southwest: Confederate president Jefferson Davis of Mississippi (the "Old Southwest"); Lyndon Johnson of Texas; and George W. Bush, the latter a Southwesterner by adoption. Under such leadership, the southern influence, it could be said, helped to hasten the national crises that resulted in aftermaths not at all anticipated. "From the Quasi-War with France to the Vietnam War," argues David Hackett Fischer, both coastal and inland Southerners "strongly supported every American war no matter what it was about or who it was against. Southern ideas of honor and the warrior ethic combined to create regional war fevers...
Moreover, the emotional defense of honor's principles continues with special emphasis in the military culture of the nation, in which the southern presence is quite conspicuous...Thus, the intensity of the southern inclination toward the "warrior ethic" has helped to shape the meaning of honor even when it is not recognized as the compulsion it is. This code of conduct embraces these elements: that the world should recognize a state's high distinction; a dread of humiliation if that claim is not provided sufficient respect; a yearning for renown; and, finally, a compulsion fo revenge when, in both personal and collective terms, repute for one or another virtue is repudiated. What is honorable is also supposed to be ethically above question, even approaching the plane of a masculine purity of conscience under the rubric of conducting an Augustinian "Just War." Yet, invocation of this form of honor could well hide highly questionable reasons.
What we can clearly ascertain is our nation's current militaristic, imperialistic behavior is not occurring by accident. It stems from the crazed heritage of Southern honor.
