Video Shows a Fearsome ISIS

Yes it's a well-edited propaganda video but still military experts in U.S. alarmed by what it shows: ISIS fighters in Iraq as apparently very well-trained and well-armed, partly with U.S. gear (such as night vision goggles) and weapons.  Plus various things that can be used against aircraft.  Hey, we gave them more than a decade of experience and now tons of our weaponry left behind by fleeing Iraqi forces.
