Years go, I wrote that Turkey is in my opinion the world's most interesting country in geostrategic terms.
Recent events have added yet again a small piece of confirmation for this: Turkey has turned away from good neighbourhood policy with Syria's government towards good neighbourhood policy with the apparent majority of Syria's people.
The recent intercept and forced landing of an aircraft en route from Russia to Syria was more than a petty intercept of some military supplies: It was also a confirmation of the fact that due to Turkey's central role (including control of the Bosporus) Turkey is the decisive brick in the wall that separates the great power Russia almost entirely from its protégé, the Syrian government.
The only access Russia still has to Syria is a long trip through the Strait of Gibraltar, either with a very long range military aircraft or with a warship, for all other kinds of vehicles could be intercepted without too much of an éclat.
This is a reverse replay of the U.S. predicament during the South Ossetia War, when the U.S. was geographically too far away to intervene with anything meaningful but long-range bombers (while Turkey had its rather large military right next door). It chose not to intervene with (little) force, just to send a paramilitary ship with IIRC "humanitarian supplies" as a mere gesture.
We can take this as a reminder about Turkey's central geostrategic situation in European and Mid East affairs, but we could also take this as a reminder about the importance of geostrategy in general. Both might be done in great power capitals and the former version may be preferred in Ankara.
In the end, such reminders may lead to more effort spent on geostrategic great power gaming. This, of course, is unlikely to be good news, for effort spent on such government pastimes does not tend to benefit the represented people much.
