Was the American Revolution a 'might makes right' argument? Or was it, as with the Civil War, a matter of the winning side wanting it more? That the victors found their cause worth fighting for more than the losers did?
You really need to study some history before you post nonsense. Lack of motivation for the cause had absolutely nothing to do with the Confederacys defeat. If anything the South was much more united in support of its cause than the North. The Souths only real hope of winning, in fact, was reliant upon this division. The idea of going to war to prevent secession was Lincolns goal, but neither that idea nor Lincoln himself were particularly popular at the beginning of the war. This became even more pronounced with the seemingly endless string of Southern military victories in the Eastern theater. The Souths best chance to win was to parley those victories into increased Nothern opposition to the war and force a negotiated peace recognizing an independent Confederacy. It was only Union successes at Gettysburg and Vicksburg that began to turn the tide. Shermans occupation of Savannah then ensured Lincolns re-election and the eventual Northern victory.
The a South lost primarily because of the larger population and industrial base of the North. It is true that lack of state cooperation with Daviss government hampered the war effort, but that lack was due to the adherence of states to the cause, not opposition. The Confederacy was founded on the basis of preservation of slavery and maintenance of states rights. The insistence of states on maintaining control of their own troops often was harmful to the war effort, but was a consequence of the cause, not an abandonment of it. Some soldiers certainly began deserting late in the war, but that was a consequence of the defeat that they saw was inevitable, not a cause of that defeat.
"wanting it more"? LOL! Yeah....I'm sure that massive material support from the rival superpower and them providing troops and even lending the colonial secessionists their navy had nothing to do with it. It was all about "wanting it more".
