Yes, Zarif is saying that the man who eagerly signed the decree calling for the genocide of the Jews of Persia is a hero for later countermanding that decree at his wife's behest.
This would be considered a high form of Purim humor if anyone else had said it.
(His assertion that Iran "gladly" took in Jews during the Holocaust is an exaggeration as well. One Iranian diplomat did save hundreds of Jews, confident that the leader of Iran at the time who was very good to the Jews would back him up. Also, several thousand Jews were among over 100,000 Polish refugees who had been interned in the Soviet Union who ended up in Iran in 1942.)
