I haven't seen him mention war with Turkey but I can't be arsed to go back and check. But those particular posts had nothing to do with Turkey - they're about people going to Syria to fight - the only link to Turkey is that the group they're fighting alongside is an ally of the PKK, which seems pretty tenuous to me.
I can see how it would seem tenuous to you, because you don't have a personal stake in this conflict. I hope you can see why it seems more important to me.
There's a power struggle going on at the moment which will determine the politics of the region for decades to come. If the PKK come out on, or near, the top, they will us that situation to increase their attacks on Turkey.
In fact attacking Turkey is their raison d'etre.
What am I supposed to think of someone who's willing to post up pictures of tanks and comment, essentially, "go PKK, more soldiers for you, more weapons, more power to your elbow?"
