American President John F. Kennedy announced a naval blockade of Cuba on October 22, 1962. For the next seven days, the world stood at the very edge of a nuclear war. American school children practiced duck and cover drills. I remember those quite clearly – and the uselessness of them for our school. We all went into the halls and sat with our backs to the walls and covered up. Under the glass skylights that ran the length of the corridor. I don't think our principle quite grasped the concept.
Sadly, JFK would not be welcome in the Democratic party of today. Ask Joe Lieberman.
