Meh... he was a "great" general in the military sense, i guess. So were (off the top of my head) Erwin Rommel, Yamashita Tomoyuki, and Võ Nguyên Giáp. Gee, what do all these have in common?
"Great" generals that used their gifts to attack the United States of America. I’m sure Trump thinks Lee was a great patriot. Which, oddly enough, seems to be a common delusion of Americans that attack the federal government.
One wonders if Trump would praise Bo Bergdahl if he had joined the Taliban, commanded their army, and killed 600,000 Americans. "what a great general & patriot"..SAD!
