Erdogan didn’t get what he wanted from his meeting with Putin this week and isn’t willing to accept what all those parties involved have said....that the Syrian Army should control the area Erdogan covets so much.
So he ‘s gone ahead to do his own thing as he usually does anyway....because he can.
He can? Maybe.
The missing part is air power. If someone closes the air space with technology or gives air support, Turkey may not be nearly as effective as he projects.
Quite frankly, he could lose.
Lots of people with grudge to settle with the Dog.
