Your post was well written and thoughtfully laid out; although, it can be misleading to readers. There was no rebellion, insurrection, or domestic violence. Was there any Southern State legislature claiming they wanted Assistance for such events? No. The only transpiring event to ever take place was the Sovereigns whom created the Federal Government deciding they wanted to re-assumed their authority that they delegated. Nothing more & certainly nothing less. That very limited part of their Sovereignty that they delegated to their agent was again theirs, and theirs alone.
The protecting against invasion part is very interesting! It figures this didn't apply to them blue coats....s/
Sorry, but the real truth is never "misleading."
Idabilly: "There was no rebellion, insurrection, or domestic violence."
Only in Southern sympathizing history books.
In actual history, there were all of those things, beginning in some cases before a state officially seceded.
Long before firing on Fort Sumter, Southerners forcibly seized dozens of Federal forts, armories, ships, customs houses and even a mint.
Even Southern firing on Federals supporting Fort Sumter did not begin under the "devil" Lincoln, but in January, under Southern-sympathizing "dough-face" President Buchanan.
And Southern forces did eventually invade every Union state and territory surrounding the Confederacy, including Maryland, Pennsylvania, Kentucky, Missouri, Oklahoma and New Mexico.
Idabilly: "Was there any Southern State legislature claiming they wanted Assistance for such events? No."
No, but there were Union states which did.
And there is also a major issue of pro-Union counties of several states which did not accept secession -- including western Virginia, eastern Tennessee, and western North Carolina.
All of these states, plus Arkansas had refused to join the Confederacy, as long as the issue was only the protection and expansion of slavery.
But many of those states' citizens had no interest in slavery and wanted to remain in the Union.
Finally, we might note that after the South fired on and seized Fort Sumter Lincoln declared an insurrection, on April 15, 1861.
The Confederacy then declared war on the United States, on May 6 -- long before a single Federal troop had crossed a single Southern border.
So, who would ever expect to declare war on the United States, and not be defeated unconditionally?

So you keep saying, and saying...
But you can't just walk away from a legal contract without an adequate settlement of accounts, and that constitutionally requires the approval of Congress.
Certainly that was Lincoln's conviction, and it's mine too.
