They have to all intents and purposes shot down an allied aircraft in the fight against ISIS, which makes them, and any supporting NATO countries the bad guys.
I registered just to refute this.
(1) Russian planes have been striking
Turkmen targets in Latakia province near the Turkish border.
(2) Turkmen have been fighting alongside the Free Syrian Army (the "moderate" rebels), not ISIS.
(3) Nor is ISIS at all operating along that stretch of the border.
(4) Russian maneuvers in this area are entirely about protecting Assad's rear, not about the fight against ISIS.
(5) Turkey's strike is politically motivated indeed, but intended to deter Russia from attacking their ethnic kin.
(6) Conclusion, this attack had nothing to do with ISIS, one way or the other.
