If we had not been trying to oust Assad, Putin would not have had a reason to delve into the middle east. Obama created this mess on top of the mess that was already there. Now all we can do figure out how to live with the new reality of increased Russian presence in the ME.
It wasn't Obama. He was just a lazy figure head who was a perfect multicultural face for the globalist puppet masters. As much as it would be easy to simply blame it on Obama, the same forces in opposition to Trump from Deep State let Barry know what they expected him to do. The taking down of Iraq, Libya, Syria, Iran,... has been in the works by the puppet masters for at least a few decades. Even Clean Break has been around for two decades.
But the globalist puppet masters have moved beyond the Middle East. They have been emboldened by how easy it's been for them manipulate and take down anyone and anything not 100% acquiescent to their control. Now they have convinced half of the West that there is now a big white Christian country that is the biggest threat. Russia. And when Russia stepped in to thwart the complete destruction of Syria by Islamists they became "the biggest threat" to the globalists. The most uncomfortable thing to the globalists is the cross of Christ and for a very long time they have been working to eliminate Christianity. Even if they means flooding the Christian West with Muslims which will affect themselves indirectly. They are the scorpions of Aesop's fable.
Russia is not a threat. Anybody who says Russia is a threat is a liar or a fool. Russia is an obstacle to the mad desire to rule the world by force of arms and capital markets. And of course, from what we've seen in Syria, they stand in the way of the annihilation of Christians.
