I don’t agree with the conclusions of the author in 5,6 or 7. I believe the others are correct for the most part.
Items 5, 6 & 7 focus on the sequence of events leading up to the Confederate declaration of war on the United States, May 6, 1861.
If you are not conversant in those events, then I can recommend books on the subject.
Of, if you wish to cite facts which prove those points wrong, I'll be happy to respond.
