I believe the trap is set with Raqqa. Nothing short of Turkey intervening on the side of ISIS can prevent that battle happening. And I believe the Coalition (headed by Kurds) can in fact take it with our air power. I am not sure about armor. I understand Turkey lost a lot of tanks already, or that is the rumor (some evidence). Urban fighting with armor is still susceptible to shoulder launch weapons. I'm sure the US provided those to people who morphed into ISIS.
Yep.
Piles of TOW missiles were provided to "moderate" rebels, who promptly "lost" them to ISIS and al Nusra (al Queda's local team)
