I've often lamented in the past that the "genius" Presidents get us involved in F***ed up sh*t. Carter was supposed be "brilliant." Kennedy was supposed to be "Brilliant". Woodrow Wilson was supposed to be "Brilliant, and of course Abraham Lincoln clearly was "brilliant."
As is usual with "brilliant" intellectuals, they are often "too smart by half". They end up making a mess because they had the arrogance to think they knew what was going to happen, and it turned into a horrible mess because they overestimated their own powers of perception.
Yes, Lincoln lit the fuse on a very horrible war, and even though he was warned by his cabinet, he did it anyways because he thought he could handle it.
And yes, after so much bloodshed, they wanted to exploit a religious angle and claim it was "God's work." It was the only excuse that people would accept for all the horrors they brought to the people of both North and South.
This is the correct assessment of the late “unpleasantness”.
