I thought back to a Korean War vet I’d watched get patted down in the airport at Rapid City, S.D. I’ve written about him before but I’ve never been able to forget his clear, watery eyes and tremulous voice. Here was a guy who’d served his country and was proud of it. He had on a ball cap from the ship he’d served on, a light jacket, and pressed pants. But the country he’d served had either ceased to exist or had become unrecognizable to him.
