“The problem was there was not a framework in the constitution for peaceful state succession.”
This is a false statement. The procedure for the secession of a state was the same procedure used for the accession of a state. The secession or the alienation of a state or its territory required the same legislative acts in Congress and the states as were used for the accession of a state to the Union.
I don’t remember reading the procedure for leaving the union mentioned in the copy of the Constitution I read. Perhaps you could point me to the article that specifically says what you stated, or are you just making it up?
