This thread is in response to an off-topic discussion in a thread on Israel's right to exist.

As to the south not being able to survive independently, they certainly thought they were able to. They also did it successfully for the duration of the Civil War. Regardless of whether they could or not, it was their decision to make and Lincoln had no right to use force to make that decision for them.
