I'm sorry I took so long to respond. One thing I've learned to deeply appreciate over the years is correction, especially in the form of constructive criticism you gave. Thank you, and I mean that sincerely.
I will say that the references I can find don't seem to state which is dominant in Turkey, but do support your point that a Salafist would never ally with a Shi'ite, especially since (I just learned) they are strongly influenced by Wahhabism.
I have to disagree about Erdogan's motives towards Armenia - I think he's much more concerned with stopping Russia from spreading their influence, which is why Turkey's forces have opposed Russian mercenaries in both Syria and Libya.
You're right that Turkey will not make war on a NATO member. It does seem more like the saber-rattling about Cyprus is more about "speaking to his base" in the same way Chinese leaders keep their "conservative cred" by threatening to retake Taiwan, but really don't want to invade.
I don't think Armenia will try to retake NKB for a long time, not unless there's a real game-changer such as both Turkey and Azerbaijan falling into deep economic turmoil, or Russia actually being both willing and able to put forth sufficient force to back Armenia's claim.
All this just goes to show that I really need to learn to dig deeper - and ask those who know far more than I do - before I go opening my digital mouth. Again, thank you :)
