A smile with a knife.
In one form or another, it is clearly still with us.
I will add that most people don’t know the song “Mack the Knife” is an adaptation from a Bertolt Brecht play in which a literal knife-killing gangster is used as a figurative moral equivalent to Capitalist exploitation.
Brecht, of course, was a Communists of sufficient piety that he was allowed to come and go from East Germany as he pleased. They never had cause to doubt his loyalty, and were never disappointed.
