Interesting. Makes you wonder if Lincoln really WAS trying to hold the union together or afraid that the south would overpower it and struck first.
The South lacked the finances, manpower, equipment, and industrial capacity to overpower the United States, let alone try and conquer South America or a part of it. The may have had a shot at some of the islands in the Caribbean.
I never once in my life ever thought of that. The South did have very capable generals. Maybe the problem was "President" Davis of the Confederacy tried to act like a general and hampered General Lee.
