It Ain’t Over Until It’s Over

I recently read Grant by Ron Chernow.
It’s a really good book.
And I learned, in detail, something I never knew.
I have heard the concept bandied with ecumenical jocularity, but I have never had reason to take it seriously.
Chernow has lifted the curtain: the Civil War never ended; it has just morphed over the last 143 years into an increasingly sophisticated guerilla action.
