I call BS.
Sometimes I think we would have been better off by halting the expansion of slavery and letting it die a natural death. It was already on its way to becoming too expensive for the south and they would have eventually driven their own slaves away to make their own way in the world.
Unfortunately slavery taught them dependency which exposed itself with those who followed Sherman across the south. They had become like lifelong prison inmates afraid of freedom. Sadly the democrats took advantage of the situation and returned them to the political plantation.
Oxymoron
There are no “very smart” white house aides. Therefore, this is created BS.
