The exchange of sanctions between Europe, the U.S. and Russia reminded me of an episode from Harrison’s book “The Ethics Specialist” where leaders meet at the border line:
“I hate you, Chuck!” he said.
“I hate you, Fassimba!” replied Chuck.
The exchange of curses seemed to be as compulsory as the pa-de-de in ballet. Both shook with guns, shouted several threats to each other, then sat down and began to talk peacefully.
