It's really just a cynical Machiavellian machination on the part of Erdogan. He's only doing this because he thinks it'll get him his F-16s, but even that may be no longer a thing considering Turkey's recent posturing against America's Sacred Cow: Israel.
Yep, pretty much what I predicted in the "Which country do you think is most likely to turn on the US" thread, Turkey going along to get along like a good little NATO soldier. But still, fuck Erdogan. He's just as bad as Putin if not worse.
