Seems Turkey miscalculated presumption of NATO support -They don't need Nato's support. They have got US support. It's just an orchestrated ugly game planned beforehand.
violating airspace -Zenaan, it's not just about the airspace. It's about the fact that Russia's jet was not threatening Turkey. The "funniest" thing is that he was also EMPTY from bombs because he was AFTER his mission where he dropped everything and was on the way home.
