Margaret Wente has obviously forgotten that Castro was a Trudeau family friend and was close to Justin's deceased brother, Michel and was invited by the family to be a pallbearer at Pierre's funeral. How does she expect him to react to this man's death - do a little dance and sing "Ding dong, the witch is dead"?
Aside from his personal connection, diplomacy and civility require that he not use the occasion of a man's death to list his sins.
