Making War on Americans, including civilian NON combatants, is indeed something unique amongst all United States presidents. Notwithstanding the conquest of American Indians. Lincoln is a better arguement for invading the Sudentland than invading Iraq. Must be why Hitler agreed with his views of nationalism.

From an interview of 'The Real Lincoln' author, Thomas DiLorenzo by the Ludwig von Mises Institute, 6-3-2002:

DiLorenzo: Lincoln suspended habeas corpus, he jailed political opponents and newspapers writers, and violated the letter and spirit of the Constitution at every turn. I document all this, as does Jeffrey Rogers Hummel. It is amazing how the Lincoln cartel goes to such lengths to justify these activities. The difference with my book is not so much in the facts themselves, though I bring out many that Lincoln partisans would rather forget, but that I don’t go to enormous lengths to provide twisted rationales for Lincoln’s behavior.

Hermann Belz, for example, says that Lincoln was not a dictator because he allowed the election of 1864 to take place. But Belz doesn’t mention how Lincoln rigged this election. Federal soldiers had the opposition jailed. His confiscation acts covered everyone who would dare dissent from the Lincoln line. He patrolled the voting booths to kick out Democrat voters. He also orchestrated the secession of West Virginia just to gain a few electoral votes. In short, this was Mugabe-style democracy.

Mises.org: Were you previously aware that the Lincoln partisans were so vehement?

DiLorenzo: What you have here are several very well-funded neoconservative foundations that are using Lincoln mythology to advance their current political agenda of strong national and executive power. In my debate with Harry Jaffa recently, one of the last things he said, which drew a lot of boos from the audience, was that September 11 proves that we need a strong central government. This is very revealing. Essentially, these neoconservatives want big government just like Lincoln did.

So here I am, this one professor at a liberal arts college and I have these dozens of people on the payroll of foundations ganging up to call me names and otherwise smearing anyone who questions the mythology of Lincoln as a great liberator. I’ve noticed over the years that anytime anyone questions this they swing into action. But I suppose I’ve been taken aback at their tone and tactics.

Mises.org: When the Soviet Union was breaking up, didn’t Gorbachev cite the Lincoln precedent to justify that empire?

DiLorenzo: Certainly, which shows that he knew something about the role that Lincoln played. The Baltic states wanted to secede, so Gorbachev said that by trying to prevent it, he was doing no more or less than Lincoln did. In fact, despots ever since Lincoln’s time have cited his actions as a moral precedent to crack down on political dissenters. All the great tyrants of the 20th century were consolidationists, including Adolf Hitler.

Mises.org: What did Hitler have to say about the American Civil War?

DiLorenzo: During my debate with Jaffa [see complete transcript], he cited some source where Hitler supposedly said that it was too bad that the Confederacy lost the war. But no one ever heard Hitler say that. And we have Hitler’s own book, Mein Kampf, which makes a case for the German union in the same terms that Lincoln made the case for American union.

Hitler writes that “individual states of the American Union . . . could not have possessed any state sovereignty of their own. For it was not these states that formed the Union, on the contrary it was the Union which formed a great part of such so-called states." This was also Lincoln’s view.

Hitler goes on to say: “Certainly all the states in the world are moving toward a certain unification in their inner organization. And in this Germany will be no exception. Today it is an absurdity to speak of a ‘state sovereignty’ of individual provinces.” And further: “In particular we cannot grant to any individual state within the nation and the state representing it state sovereignty and sovereignty in point of political power." Finally: "National Socialism as a matter of principle, must lay claim to the right to force its principles on the whole German nation without consideration of previous federated state boundaries.”
