Third, Iran has already provided intelligence support to both Iraq and Syria. It has been providing Human Intelligence (HUMINT) and Signals Intelligence (SIGINT) for these countries using unmanned aerial vehicles and intelligence forces. Indeed, it should not be forgotten that there is a history of intelligence and security collaboration between Russia, Iran, Iraq and Syria. These countries have already, separately from one another, signed military and security collaboration agreements.
Finally, Russia’s reassuring of Israel regarding the new developments in the battlefields in Iraq and Syria makes the situation more complicated.
It thus appears that Iran believes that the potential disadvantages of Russia’s involvement are greater than its advantages. It is against the backdrop of the latter that one may view reports that “hundreds of Iranian military forces have entered Syria in order to perform ground operations inside that country.”
In conclusion, based on available data, it appears that Iran is naturally not willing to concede its supreme positions in Iraq and Syria to another country. However, Tehran will welcome and support Russia’s desire to battle terrorism in the region.
