It's Pronounced Nu-cu-lar, Dummy. The 'S' is Silent.
Anybody that can name the heading reference wins my sympathy.
So casually browsing Pajamas Media and following some links led to this: 20 Mishaps That Might Have Started Accidental Nuclear War. My personal favorite:
At around midnight on October 25, a guard at the Duluth Sector Direction Center saw a figure climbing the security fence. He shot at it, and activated the "sabotage alarm." This automatically set off sabotage alarms at all bases in the area. At Volk Field, Wisconsin, the alarm was wrongly wired, and the Klaxon sounded which ordered nuclear armed F-106A interceptors to take off. The pilots knew there would be no practice alert drills while DEFCON 3 was in force, and they believed World War III had started.Immediate communication with Duluth showed there was an error. By this time aircraft were starting down the runway. A car raced from command center and successfully signaled the aircraft to stop. The original intruder was a bear.
Not among the top 20 is a much more harrowing account of a 1983 computer glitch that told the Soviet equivilent of NORAD that US ICBMs were on their way. A Lt. Col. decided under duress and at the risk of losing Soviet nuclear deterrent that it was probably a glitch. He prevented WWIII from going hot, but was dismissed because he was no longer politically reliable.
This is a subject that I rarely dwell upon, given a relatively positive view of MAD doctrine (living in Germany during the Cold War does that). However, given that the top 20 were mostly NATO near-misses, and it's probable that the Soviet system was more prone to err, I will suggest that is only by the grace of God that we are alive. Then again, we already knew that.
