A question I haven't seen asked yet. As the Russians were shot at by 'moderate forces', killing one of their pilots and a naval infantryman, and destroying a Mi-8 helicopter being used in the rescue, does that now make them a legitimate Russian target?
And the so-called "moderate" US-supported forces also shot at the aircrew as they parachuted down, killing one, then used a US-supplied weapon to destroy the Mi-8 rescue helicopter.
I find it pretty tiresome that US and UK politicians use every sound-bite opportunity to portray Assad as a brutal tyrant who "murders his own people" while clearly - as in all civil wars - all sides are driven to equal levels of brutality.
