It is quite clear now that with every victory over ISIS, Tehran and it terrorist proxy, Hezbollah, are ready to fill the vacuum.
The fight against ISIS was exploited successfully by Tehran, for two objectives. The first – to establish an arc of influence, spreading from Tehran to the Mediterranean. The second – to consolidate and strengthen the “resistance axis”. Both objectives seem to have been achieved.
Several analysts have already declared Iran the winner in Syria (see for instance the Bloomberg article “as Syria crumbles only Iran is a sure winner“, and the paper issued by the Middle East Forum asserting “and the winner in Syria is Iran“). The same for Iraq. The NYTimes reckons that Iran dominates Iraq, and that “from day 1 Iran saw a chance to make a client state of Iraq and transform Iraq into a jumping off point to spread Iranian influence around the region, and in that contest Iran won and the US lost“. The commander of Iran’s Quds force, Kassem Suleimani himself, boasts that Iran now has the upper hand in the region. But it’s not really Tehran who is filling up the vacuum of ISIS, it’s Hezbollah since Hezbollah acts as a non-state proxy which is free to fight all of Tehran’s wars.
Ideological similarity leads to cooperation, as can be seen from historical and current cooperation between Tehran and al-Qaeda. It has already been exposed that Tehran has a long term secretive alliance with al-Qaeda. Recently, Somalia sent an urgent letter to the American ambassador, raising concern regarding cooperation between an al-Qaeda affiliate Al-Shabaab and Iran on the mining of uranium. According to the Somali warning, “global stability is at stake”. Apparently, the alliance is still at work.
Such cooperation or alliances should not come as a great surprise. Radical groups may be stark rivals, but with time, the common goal is a uniting factor. Tehran, al-Qaeda and ISIS are, ideologically, not so far from each other. They all support Islamic views of global domination, strong anti-Western inclinations and the goal of an idealized government based on Shariah law. They all engage in terror as a justified means. The strong alliance between Iran and Sunni elements (like Hamas, Turkey and Qatar) demonstrates the fact that the Shiite-Sunni schism can be overcome if the mutual goals exist. As al-Monitor claims Tehran is focused on improving relations with Sunni actors in the Middle East. In their eyes, the end goal justifies the means.
And when that goal is to export the Islamic revolution, it’s Hezbollah which is on the front line. So, you can allow yourself some comfort in knowing that the monsters of ISIS are finally on the run but remember that the guys in Hezbollah are much closer to ISIS than you would hope for.
