Problem: Southerners argued that their states had the right to break away from the Union. Because these states had originally joined the Union willingly, they also had the right to leave if they so chose. Our nation was founded, after all, by colonies that chose to separate from an oppressive government. How would you respond to that argument? What is your opinion of the Northern decision to invade the South and force the seceded states to stay in the Union? Explain.
