If smaller firms know the process, where to start, how to connect and communicate, they can potentially have a better shot at reaping the benefits of the Iranian economy. I would be delighted to shed light on the nuances, but Illustrating and explaining the whole process is out the realm and given space for this article.
Chemical weapons attacks are notoriously difficult to substantiate. The debris they leave is hard to detect from satellite images. To positively identify a toxic agent, you need to analyze affected blood samples. But in Syria, and in particular in the Damascus suburb where the December attack occurred, the specialized medical equipment needed to conduct these tests is in severely short supply.
While Iranian leaders project that they are fighting ISIS, Iranian forces are not anywhere close to an ISIS stranglehold. Instead, they appear to be battling Syrian rebel groups, including the Free Syrian Army, to force them to retreat or prevent them from capturing more territories in Aleppo, Latakia and Damascus.
Russia's presence in Syria has little to do with fighting ISIS and everything to do with propping up the regime of Bashar al-Assad. More international forces getting directly involved in the fighting on Syrian soil is complicating and prolonging the Syrian conflict whilst civilians continue to suffer.
If all we do is destroy ISIS, other terrorist organizations will spring up in what would continue to be an ungoverned space. We need a coherent political solution, which will best be constructed through diplomacy, not the war rooms of the Pentagon, NATO and Moscow. And we can use history as our guide.
