The U.S government has always placed a premium on keeping its secrets, and this has extended into its messaging to civilians as well, though today the emphasis is more on being aware of what we see and hear (If you See Something, Say Something) rather than what we say. But during WWII, wartime posters clearly sent the message that careless blabbing could carry dire consequences.

Last week's meeting in the Oval Office between Donald Trump and high ranking members of the russian government, in which classified information was allegedly revealed, reminds us that trusting information to someone with "loose lips" could ultimately sink ships and all of us with it.
