The justification is quite simple really. Keeping the southern territory was in the best interests of the United States. In the case of the Revolutionary War, it was in the best interests of the Americans to be independent, and in the best interests of the British to keep their colonies. The current administration perceives that it is in our best interests to take Iraq.

What other justification do you need? If the country is cut in half, then the chances of being destroyed by other enemies doubles. The Confederacy would have eventually gained much more power and presented a real threat to the Union. Then when the United States loses a big war, somebody like you will say that Lincoln was a bad president because he failed to protect the union, which led to its eventual defeat.

There are no "morals" or any such thing that govern whether wars are right or not. On a global scale, the world is essentially anarchy, and therefore, no justication is ever even needed to do anything, since nations do not have to answer to anybody. So stop saying that killing so many people is the reason that Lincoln was a bad president, and DO tell us why it was not in the best interests of the United States.
