“There’s only one way out of the union - the same way they got in. And that is by mutual accord.”
That’s not what Abraham Lincoln said.
jefferdondem: "That’s not what Abraham Lincoln said."
A very young Abe Lincoln did once argue for a seemingly unlimited "right of secession", but even then young Lincoln recognized the reality that secessionists must have the capabilities needed for success.
In office, so far as I know, Old Abraham Lincoln never argued against secession itself, but did resist Confederate military aggressions against the Union.
As the war dragged on, Lincoln's war-goals grew eventually including complete abolition and citizenship for freedmen.
