It wasn't met with violence by the feds last time. The secessionist started the violence.
I wasn't specifically referring to the Civil War, I was referring to your implication that the only possible result of secession is civil war. But since you bring it up, how exactly was the Confederacy supposed to react? Lincoln was talking about preserving the Union at any cost in the lead up to the Civil War. Now, if you are a secessionist and you hear that, wouldn't you essentially take that as a declaration of war? I would because that's the head of the federal government basically telling you that he doesn't care about your right to self-determination.
So the shelling of Fort Sumter could just be seen as a preemptive strike against an inevitable aggressor. Plus, all Lincoln had to do to at least delay open hostilities was surrender Fort Sumter to the CSA. No one can say Confederate forces didn't give the Union garrison ample opportunity to resolve the siege peacefully.
Is there any reason we can't do that now, without literally ripping the country into pieces?
Yes there is a reason. That reason being that both Democrats and Republicans are getting increasingly tired of living under the thumb of federal law when it comes to running the states they control how they see fit. Beyond the party politics, there are also regional issues that the federal government has shown it is completely incapable of handling, yet their regulations and laws keep regional and local authorities from being able to take the lead and deal with those issues. Right now, we have a situation where no one is really getting anything they want out of the current arrangement, so maybe it's time we all just go our own way.
So basically, it boils down to two things: Increasing frustration with the federal system in general among both citizens and state governments, and a growing desire among local authorities for greater autonomy without allowing politicians from the other side of the country having a say in their affairs.
I'm not sure the Eurozone is exactly a model right now. I mean, why would a prosperous region like the Northeast want to be in a simple trade relationship with Mississippi or Oklahoma? Can those states really support themselves without the rest of us? We put more money into the federal coffers than we take out, and I don't know if the farming states want to replace that with whatever trade deals they can negotiate with us.
Again, assuming the dissolution is peaceful, I could see things remaining relatively unchanged economically. I guess a better way to describe what I'm envisioning is something that's halfway between the relationship between the states during the Articles of Confederation days and the system we have now. Economically, we'd still function as a single nation, but politically each new region, however it ends up being divided, would be free to establish its own laws and even it's own system of governance. I don't know if such an arrangement would even be possible, but that's what I'm envisioning.
Secession is illegal.
Not really. The Constitution is completely silent on the matter and even after the Civil War, no legislation or amendment to the Constitution establishes the legality or illegality of secession. And according to the 10th Amendment, any powers not specifically given to the federal government go to either the states or the people themselves. So I'd say a pretty strong argument could be made that the power to decide whether or not to remain in the Union lies with the states.
The Civil War was not a court case, it was a military conflict. As such, it's outcome has no legal bearing on the issue of secession. Now there is one Supreme Court case dealing with secession: Texas v. White. The ruling in that case says that only unilateral secession is illegal. However, the ruling does also say that secession by successful revolution or through consent of the federal government would be legal. So there actually is a road to secession. The federal government just needs to set their pride aside and agree with the will of the people in a given state. I mean seriously, if a state votes to leave, why would the federal government want to keep them around anyway aside from the "we need to put these filthy rebels in their place and show them who's boss!" mentality.
RE: Commodore's map, y'all can't be discussing drawing up new borders and completely ignore Cascadia.
Sorry, Tim and I have already negotiated the new border agreement. You'll have to take the Cascadia issue up with your new Californian overlords.
