re: #47 EPR-radar
While I think some leadership hangings could have been justified post civil war, the idea of forcibly reconstructing the South on non-racist lines is an unrealistic anachronism. If nothing else, there was not nearly enough political will in the North for that.
Also, the US Confederacy was much more deeply entrenched in society than either the Nazis or the Japanese militarists. Removing that aspect of the US south by military force is also unrealistic.
Wait, didn’t they totally do that in 1865?
