What rebellion?
Lincoln rebelled against the Constitution!
[...] and [The United States] shall protect each of them [the States] against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened) against domestic Violence. Figure, Lincoln didn't think this applied - Since he was the one invading......
or
Did he illegally invade a sovereign Country - Which is currently under occupation?
I'd have to say "yes" -- Congress never delivered articles of war.
The one the Southern states initiated in 1861 and fought to an unsuccessful - from their viewpoint - conclusion in 1865. Did you sleep through all your American history classes in school?
Lincoln rebelled against the Constitution!
The actual clause of the Constitution you should be looking at is Article I, Clause 8 which provided for "calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions..." With Congress not being in session, the Militia Acts gave Lincoln the authority to do that in their absence.
Figure, Lincoln didn't think this applied - Since he was the one invading......
It didn't apply because the Southern states were the ones rebelling.
Did he illegally invade a sovereign Country...
There was no sovereign country called the confederate states of America.
...Which is currently under occupation?
Hey, Delta flies out of the country as well as into it. Feel free to flee the 'occupied territories' and find another place to plant your butt.
