I do not condone terrorism, but these guys had it coming. They've supplied the drones to spot and kill not just Kurds, but also Syrians, Iraqis, Libyans, Russians, and Armenians. They are one of the chief enablers of Erdogan's Turkish imperialism project. This is like some terrorists hitting an office belonging to General Dynamics.
Turkey is also the current homebase of ETIM, so it cannot pretend to be China's genuine friend. Erdogan himself had also failed to confront the true terrorists, the Zionists, so this will become his legacy: a closet pro-Western snake. Live by the sword, die by the sword.
