I do not doubt for a second that the Civil War centered around slavery.
But countries come and go. A more decentralized, non-capitalistic model of socio-political/econonic organization is whats needed for the people here. I do not advocate for reaching towards any sort of utopia, as down that road lies a heap of atrocities regardless of the specific vision to which the utopianists in question aspire. I simply think that the US 50 state model has outlived its usefulness and that it is about time for world history to proceed under the aegis of the Eastern powers, China and India.
