I liked this video with Ted Postol and Col. Wilkerson. Postol describes the theory behind the "superfuze" on the W-76 nuclear warhead and why it's destabilizing. Wilkerson describes the so called escalate to deescalate tactical nuclear war ploy. I cued the video to Wilkerson's presentation. Postol had an article on the superfuze in 2017 in Bulletin of Atomic Scientists. His presentation is before Wilkerson's.
