Right, but what makes the "states" somehow a more legitimate entity than the federal government? By any regard, the CSA was a rogue state, as the United States declared their succession illegal, and no foreign government recognized them. By any standard of international law, Fort Sumter was American territory.
International governments opinions do not matter, they had full legal rights to secede, Lincoln broke the law in claiming it was not legal.
Don't they? In the modern world, it is the international community that determines the legitimacy of a new state.
Only to the New world Order fools who blindly follow Natos corrupt ideas.
