Turkey has some serious issues. The biggest being Erdogan. His Islamic vision for Turkey and his Nepotism (his Son is president of the Turkish Central Bank) are detrimental to Turkeys future. As to his Army, most officers are behind bars, as are most of his airforce's pilots. So certainly not a force to be reckoned with, at this moment.
Also he has cornered himself internationally:
1) shoots down a Russian jet (pilot killed by Turkey sponsored jihadis).
2) buys Russian air defense system as the US will not deliver a US type.
3) supports the Aleppo jihadis, that fight Assad (and Russia).
4) Invades 'Rajova' and starts a killing spree (by way of jihadis), something not agreed with Trump.
5) Claims a large Economic Zone in the Medditeranian See (touches Libiya).
6) Hinders Cyprus,
Greece and Israel building a gas pipeline to Europe (there oil and gas between cyprus/lebanon/israel/egypt)
7) Kills any and all possibility to join the EU or have a special relationship with it.
So at a certain moment in the near future all these strings will coalesce and have a severe negative impact on Turkey.
I would not put any money in such a place.
