@OmSigDAVID,
The fact that making war on the United States was just about the stupidest thing the southern states could have done to preserve the institution of slavery is not an argument against that having been their motive. Not only is there no universal law that people only ever do the most efficient things to acheive their ends, history is littered with the evidence of people doing just about the stupidest things they could and accomplishing as a result the exact opposite of their goals. I cannot recommend too highly Barbara Tuchman's
The March of Folly. That the southern states acted in a puerile, stupid manner does not contradict that they acted, ostensibly, to protect the institution of slavery. There is abundant documentary evidence to that effect.
The limits of your conceptual abilities are a subject of no interest to me.
Now you're reaching even farther from reality than is your wont. Not only is it a false analogy to compare Americans from one region to Americans from another to the rather obvious distinctions between Americans and Arabs, but in fact, southerners fought for the Union, and northerners fought for the South. Probably the most efficient and modern general during that war was George Henry Thomas, a native of Virginia. The commander of the cavalry division which crucially retarded the advance of Heth's division toward Gettysburg on July 1, 1863 was John Buford, a native of Kentucky. A few days later, the city of Vicksburg was surrendered to the Federal army commanded by Ulysses Grant. It was surrendered by General John Pemberton, a native of Philadelphia. Philip St. George Cooke, a native of Leesburg, Virginia, was the father of the woman who married James Ewell Brown Stuart. Cooke fought for the Union during the war, and of course, Stuart fought for the Confederacy--as did Cooke's son.
As usual, you trivialize these issues. The more i speak with you about history, the more apparent it becomes that your knowledge of history is only superficial, it is shallow, and that this cannot be corrected because you surrender your intellectual abilities to your political obsessions. The South started that war, and it had nothing to do with an allegedly "alien" military power in thei midst. I'm sure they didn't feel that they were that alien when they were fighting the Creek War or the Seminole War, and they certainly benefited from northern participation in the Mexican War, which, as many northerners saw it, served to extend the potential territory for slave states. That it didn't work out that way does not alter the intent. The southerners responsible for that war were a relatively small coterie of self-interested slave owners who were happy enought to have the military equipment and defensive installations they used provided through the revenues from the more numerous North. To now allege that they were some noble band of libertarians is, sadly, all too exemplary or your distorted and essentially immoral view of history and of life.
