These aren't the typical WWII propaganda posters, however. They do, however, send a message that resonates today...
These remind me of an anecdote from WWI:
The French initially did not consider the American approach to the venereal problem practical. In February 1918, [French] Premier Clemenceau, in a letter to GHQ [General Headquarters], criticized the repressive policy and suggested, as an alternative, licensed houses of prostitution, which he would help to establish. The American reply denied that Clemenceau's information was correct and called for a conference on the matter. Meanwhile Pershing gave Raymond Fosdick a copy of the letter to show to Secretary Baker. When Fosdiek passed the letter on to the Secretary, Baker read it twice and then exclaimed, "For God‘s sake, Raymond, don‘t show this to the President or he’ll stop the war."
