I don't see Turkey getting kicked out of Nato unless they do something really stupid. But on that subject, without NATO, Turkey would really be in a bad situation. Erdogan wants Turkey to be considered a middle east power on par with Saudi Arabia and Iran but the arabs on the whole don't even consider Turkey to be part of the middle east power structure. They consider them more of a neighbor that occasionally has a role to play. With Russia to the east, they have minor influence in central asia but can't influence things too much when Russia decides to flex it's muscles in response.Seems Syria is not the only country that the Turks have a habit of overflying. In 2014 they have committed 2244 violations of Greek airspace in the Aegean Sea around islands close to the Turkish coast. The previous year the violations were 636 having significantly jumped because of the Greek economic crisis and the funding shortage to the Greek Air Force resulting in it's response not being as vigorous as in previous times. Maybe the Greeks need to follow an example out of the Turkish playbook. Actually maybe it's about time that NATO reevaluated Turkish membership of the treaty because they are becoming a liability.
without NATO backing, they largely (not entirely) become irrelevant and would have a limited ability to influence things much beyond hteir borders. Then again, maybe the threat of NATO expulsion might get Erdogan to behave for a while.
