In November 1994 I paid an early morning visit to my old boss, Sen. John Glenn, in his office. I had just returned from North Korea, as part of the US/DPRK Agreed Framework to safely store and safeguard spent nuclear fuel, containing plutonium at the Yongbyon nuclear site. After a while, we sat there in silence, as he stared at the model on his desk of the F-86 jet he flew as the "MIG Mad Marine" during the Korean war. I had never seen him so glum. "You know," he said, "I've regretted to this day what we did to that place. All of it was totally flattened." He then snapped back to his genial self, as we shook hands before I left.
