I started re-watching this 1964 made movie this morning while exercising, and found it holds up amazingly well. And it is even more scary than when I first saw it in 1965. I have no idea if an accidental initiation of nuclear warfare is more or less likely than in was 57 years ago, but I know that no system can be made absolutely foolproof. In 1965 I was a 22 year old single guy, getting ready for both marriage and entry onto active duty with the U.S. Army. I had little doubt in those days that war with the USSR was inevitable, but didn't lose much sleep over that thought. Now, as an old man, with five grown kids, and 12 precious grandkids, the thought of a nuclear exchange, accidental or deliberate really terrifies me. I still believe that our best protection is to have overwhelming military strength, i.e., mutual assured destruction of China, Russia, Iran and anyone else that even thinks that they can beat us, but have little faith that our current leadership is up to the task.
