Query: Rational Northern Account of Justified Union Victory

The author debunks "Southern" myths about the so-called "War Between the States" and correctly attributes the origins of the war to a greedy slave-owning patriarchy that sought to extend slavery to other parts of the US and indeed the rest of the hemisphere.He clevery refutes the Southern justifications for aggression against the US with damning authority. For example, the issue of "States' Rights" was always a red herring on the part of rapacious and racist slave-owners for the maintenence of brutal and evil slavery.The fugitive slave law could have been nullified by Northern States on the basis of "States' Rights" but the Southern States always howled about how federal law, IN THIS INSTANCE, had to be maintained.The author points out that in the South, they only obeyed those laws that suited them.This book would be a fine antidote to Foote's narrative and somewhat pro-Confederate "The Civil War" series.
