The departure of Hossein Taeb from his post as the head of Iran’s Islamic Revolutionary Guard Corps’ Intelligence Organization triggered a wave of reshuffling in the command structure of the guardsmen. But the story is more than just a reaction to Iran’s unsuccessful terrorist targeting of Israelis in Turkey and counterintelligence lapses. There are internal power struggles and a natural maturation of the Islamic Republic’s security structure that also likely figured into the decision to remove Taeb.
