I am convinced that Russia is deliberately causing chaos in Syria.
The streams of Syrian refugees cause open borders to be closed. Closed borders make the shipment of goods around Europe MUCH more expensive. More expensive goods make life more difficult for everybody. The good thing about free trade is that it make oranges from Greece inexpensively available in a German winter.
But closing the internal borders in order to control the thousands of refugees makes all goods stop to be inspected for stowaways, thereby making the cost of a winter orange much higher. Such an easy way to caused economic chaos in the EU.
By causing millions of refugees to flee to Europe, Russia makes the Europeans worried that their jobs will be taken over by a desperate refuge. It is easy to trigger this fear into a "Let's get out of the the EU."
I would not be at all surprised to learn that Russian spies encouraged the disaffected into violence. Fear is so much easier to trigger if the news shows horrible scenes of destruction.
Fear makes selling xenophobic propaganda much easier. If you do not trust your neighbor, it is easier to convince you that making treaties to support each other is not a good idea.
The EU is humanity's path to stop wars. But Russia is really upset that it was not allowed to steal Ukraine.
So Russia is trying to end up with a smaller EU. Divide and conquer, one of the oldest war games on Earth.
