 If the Founding Fathers had not agreed to leave the issue open, the United States of America would not have existed at all. Because the southern states, North and South Carolina, Virginia, would not have entered the Union. They would have formed their own country. And God knows what would have happened after that. So it was very wise of the Founding Fathers to kind of exclude slavery from the original Constitution, but put in the mechanism available to stop it in the long run. And they did. And thank God we did.
