Well his results were not what he wanted. What he wanted was to reassert control, and resume having that Southern export trade routing through his friends pockets, with all the slaves remaining in harness powering that money machine.
Now he greatly underestimated the resistance he was going to face when he started that war, and so he didn't get what he wanted when he began it.
Of course what he got instead is greatly increased federal power and control over the rest of the country, which for him and his cronies was not a bad deal.
Wasn't so good for the actual people of the nation, but was great for the cronies exploiting government connections. Of course this stuff got so bad that it came to a head under the Grant administration and the public finally noticed.
What "friends"? New York financiers and traders? Lincoln didn't many of them. Most of them didn't vote for him. And they were willing to work with the South to insure that trade continued to benefit Northern shippers and financial interests as well as Southern planters.
Do you seriously think that Northern firms hadn't acquired much commercial expertise and ability to compete over time? Or that they weren't willing to establish Southern branches and subsidiaries? As I've said, companies had branches in the North, in the South and abroad. It wasn't an all or nothing thing for them.
