If the US were to secede from the UN, could the other nations label us a "rouge" nation much as the Southern states were labeled by the unionists? Absolutely.
Could the other nations overtly, or through subterfuge, engage the US in conflict to bring it back into the fold? Absolutely.
If successful, could the other nations rewrite our Constitution and impose a government to reduce our sovereignty to international law and organizations? Absolutely.
And would the historians of the World Federation acclaim the motives and justify the outcomes of such an act? Absolutely.
Does it matter to me whether the confederate states had a right to secede? No.
Would I have forced the confederate states back into the union? Yes.
Has federalism over confederacy swung power from where it was originally held between 1777/1781 (The Articles of Confederation and Perpetual Union) to 1787/1789 (Constitution of The United States) through the Civil War and suceeding world wars? Absolutely.
Personally, I'd like to see the US bring rouge nations like Iraq, Iran and North Korea into the fold, rather than the reverse. Unfortunately, we may need to start with France, Germany and Russia.
LOL!! What absolute arrogance. Could you outline for me where it says in the Constitution of these United States where it's our responsibility, even our right, to bring other nations 'back into the fold' as you say? Are they not allowed to practice their national sovereignty either? Granted North Korea is a viable and direct threat to these United States but none of the other countries, except maybe for Russia, have the capability to attack our continental borders. But you've all the sudden decided to bring these people 'back into the fold'. And which 'fold' is that, praytell? The folds of democracy, the folds of civilized thought, how about the folds of the sphere of American Empire influence? That's it isn't it? How dare these nations have any interests in mind other than what Washington DC wants them to have, is that it?
Wait a minute, let me guess. I expect you're going to say something to the effect of 'it's not Constitutional, but it's the right thing to do' drivel. Yep, that's Constitutional < /sarcasm>
Is your post a very good one? Absolutely.
(Although I disagree about forcing the Confederacy back into the Union.)
