Many of them were coming from right wing circles, white nationalists. They have a thing for Assad[1], this is white nationalist group leader Matthew Heimbach promoting Assad. Many of them from different nations have been making pilgrimage to Damascus to meet with the regime[2].
Then one of these Nazi Assad fanboys runs down people in my own nation in a terrorist ramming attack.. I'm heartbroken. Many of us have been detailing this lot in great length for years but no one seems to of listened until we had a martyr in the US.
This is 2017, half a decade of this.
