The Kurds asked for help against the Turks. Assad ignored that, and his allies attempted to seize the Kurdish oil fields (the ones they still had -- iraq/Iran seized the others a couple months ago). Assad suddenly decides to help, but the media team his allies are using are from Hezbollah, iow, from the same pool of terrorist talent as before -- but Assad considers this a Turkish attack on Syrian sovereignty (which is a joke after nearly eight years of 20 different nationalities running wild all over and half his remaining armed forces dead). The end game will be the Turks and Syrians toasting each other out of the bronzed skulls of slain Kurds.
Thanks.
