A few blocks from where I live in Alexandria, Va., at the intersection of Prince and Washington Streets, there stands a bronze statue — fully worthy of President Trump’s epithet “beautiful” — of a young man, his head bowed, his arms folded across his chest and a broad-brimmed hat in one hand. A canteen and an ammunition bag slung around one shoulder and hanging by his side is the only indication of his military career. He is facing south.
