Wartime or peacetime, the basic idea of this film still applies: "for safety's sake, please engage brain before putting mouth in gear"; and don't assume that the guy you're listening to has followed that rule!
As Ray Bolger observed in "The Wizard of Oz" back in 1939, "Some people without brains do an awful lot of talking!" And while such people usually only damage themselves by looking ridiculous in front of people who actually do know something about the subject under discussion, sometimes they do manage to do major damage to others, whether by innocently ruining a reputation over something they've misinterpreted or by "only trying to help!" (case in point on that last: the Mr. Blabbermouth who invited himself along on a camping trip some friends and I had planned--he nearly laced our trail stew with "perfectly harmless wild mushrooms" which my friend D correctly identified as death angel mushrooms and intercepted in the nick of time!)
War or no war, Mr. Blabbermouth lives and can be hazardous to your health!
