While everyone portray Syrian and Iraq war as a war between dictatorship and freedom fighters (Syria) and between Shia, Suuni and seperatist Kurds.
But Iran gets barely mentioned, why? And you have the biased Western media often talking about Saudi Arabia and Turkey, blaming them for destabilising the Mid East.
The reality is they're taking over Syria by replacing Assad's commanders, officers and militias to Iranians. When you hear the word "militia" they're Iranian led, financed and created by them. The vast majority of the funds and backings comes from Iran, not the world and not even Russia who got their money from Iran to get new toys for Assad.
They're participating on the frontline in Iraq while the Coalition are doing the work on air. Hell, there are probably tens of thousand securing Baghdad or Basrah to secure their borders. In the eyes of Iraqis and most Kurds, they see Iraq as a satellite playground for Iran and often labelled politicians of Iranian stooges. Same goes for Yemen and Lebanon.
Why is it Iran, a non Arabic speaking country are involved behind all the mess and dragged Saudi Arabia into this turning both nations, forced each other to compete by all means using arm race and making different allies in the region which led to more bloodshed.
It is obvious without them, Assad would have fallen long time yet people still refuse, makes no sense.
