>> A spectacular attack on a military parade that killed 12 of Iran's revolutionary guards has shaken their image as an invincible force. Gunman shot dead 25 people altogether in a rare attack that shocked the nation.>>
> Although a setback, the attack could prompt a nationalist backlash and rally more support behind the military backbone of the Islamic Republic.
Iran has paraded arrested suspects on TV, and vowed to severely punish the perpetrators. History suggests the revolutionary guards might lash out abroad, says Reuters' Bozorg Sharafedin.>> Different groups have claimed responsibility for the attack, including national movements inside the country out of national movements and also the Islamic state.
Iran has also blamed Saudi Arabia, the United States, and Israel for the attack. So it's unlikely that Iran uses their missiles against any of these nations, but there is a possibility that Iran targets Saudi positions or Saudi tankers via Houthis in Yemen.>> An ethnic Arab separatist group in Ahvaz, where the attack occurred in Khuzestan Province also claimed responsibility.
Many feared the guards will result to fear tactics rather than address long held economic and political grievances that have sprout sporadic protests. And it could put moderate President Hassan Rouhani on the back foot. He already lost face when Washington pulled out of the nuclear deal that he engineered despite fierce opposition from hardliners, including the guards.
>> The revolutionary guards might use this attack to push its agenda inside the country, and might try to sideline the moderate faction including Rouhani.>>
