Lord Acton in a letter to Lee after the war:
"I saw in State Rights the only availing check upon the absolutism of the sovereign will, and secession filled me with hope, not as the destruction but as the redemption of Democracy. The institutions of your Republic have not exercised on the old world the salutary and liberating influence which ought to have belonged to them, by reason of those defects and abuses of principle which the Confederate Constitution was expressly and wisely calculated to remedy. I believed that the example of that great Reform would have blessed all the races of mankind by establishing true freedom purged of the native dangers and disorders of Republics. Therefore I deemed that you were fighting the battles of our liberty, our progress, and our civilization; and I mourn for the stake which was lost at Richmond more deeply than I rejoice over that which was saved at Waterloo."
Lee in response to Lord Acton:
"I yet believe that the maintenance of the rights and authority reserved to the states and to the people, not only essential to the adjustment and balance of the general system, but the safeguard to the continuance of a free government. I consider it as the chief source of stability to our political system, whereas the consolidation of the states into one vast republic, sure to be aggressive abroad and despotic at home, will be the certain precursor of that ruin which has overwhelmed all those that have preceded it."

General Robert Edward Lee, calling it more than 100 years before the fact.
He sure was right.
